I found some more great quotes about Ringo from some people who knew him best.
--"He had a genial expansive manner when dealing with people -- an all-embracing good natured disposition to the world at large, but he wasn't one to see his confidences betrayed. There was a pluckiness about him, a no-nonsense way of dealing with things as they came along. Ringo was a small guy with a big heart." -- photographer Robert Freeman, author of The Beatles: A Private View(1990)
--"When Ringo lost his early inferiority complex within the Beatles, his natural humor emerged, usually in the form of witty one-liners, which even John Lennon found hard to follow. Unlike the others, he remained even-tempered and placid throughout the stormiest Beatlemania years. He avoided quarrels, demanded very little in terms of VIP attention, and there was never a trace of pretension or precariousness in his makeup." -- Tony Barrow in Bealtes Monthly(Feb. 1988)
--"He's so kind. He's polite and nice to everyone. ... Richie can be stuborn. You can't fabricate charm, and Richie has charm. He's so loving and giving and generous, always thinking about others." -- Barbara Bach, Ringo's wife (in an interview during the mid-1980s).
--'As always, Ringo remains the most human. Perhaps from the one from whom the least was expected the most has been given. -- Ray Hardy, writing a review of Ringo Starr: Straight Man or Joker in Good Day Sunshine(1993)
--"Both in public and, it appears, privately Ringo's unassuming good-natured personality provided a crucial balance between John's razor sharp wit, Paul's stagy coyness, and George's somber posturing." -- Ted Greenwald in The Beatles Companion(1992).
--"About the most remarkable thing Ringo has is this unique and very funny way of looking at the world. He is absolute master of the one-liner. ... Ringo's quirky vision comes out particularly in his use of language." -- George Martin, producer of the Beatles' albums and author of Summer of Love(1994)
--"Of all the Beatles, it was fitting that Ringo would be the one to remain amicable terms with the others in the aftermath of the group's breakup, when the polar friction between John and Paul was strongest. He was, after all, always the innocent, the quiet one, the bloke who was always just doing his job and the least inclined toward politics in the group." -- Martin Torgoff in The Compleat Beatles(1985).
--"Ringo was the home body, always less publicly visible than the others. To the world he was shy, soft, puerile, down-to-earth, funny, friendly, cute, lovable, vulnerable. Appropriately, the music his friends created for him, in addition to being perfectly tailored for his range and style embodied the above characteristics as well as reflected his tastes." -- Martin Torgoff in The Compleat Beatles(1985).
--"He remained placidly even tempered. By nature he was undemanding, kind and friendly ... Ringo was not a sad person. His face was molded into a deceptively unhappy expression. Until he made the muscles move into a deliberate smile." -- Tony Barrow in P.S. We Love You(1982).
--"I think he was very important to the Beatles. I began by thinking he was just a passenger, but there was something about him that kept them on the rails. He did have a tremendous wisdom and stability of character which quite often was very important. . . . John said that in an argument all he had to do was really get Ringo on his side and that it would be all right." -- Philip Norman in Beatlefan magazine(1981).
--"Ringo Starr was the humblest, most down-to-earth of the Beatles. Like the lovable runt of a litter, he seemed to stir a mother's instinct in female fans. ...Ringo changed the least, always the group's anchor, he remained the simplest and straight-forward of the four. -- Nicholas Scaffner, author of The Boys From Liverpool(1980).
--"The songs that were subsequently written for him always seemed to emphasize the affection which the others felt for him. With a Little Help From My Friends may have been composed with deliberate irony, but anyway it was the quintessential Ringo song. John and Paul had got Ringo down to a tee. He had such a winning affable personality and so many friends that his own failings were irrelevant since he never needed to do anything on his own." -- Jeremy Pascall, author of The Beatles Story(1974)
--"He's completely open and friendly, the sweetest of them all really. . He's not self-centered in any way. . . ...Ringo is a much stronger personality than he has appeared." -- Hunter Davies, author of The Beatles(1968)
--"He never takes credit for things. I think he often underestimates himself. He does forget what good ideas he has had, because he thinks he's not creative. He says it's for the others to have the good ideas, but he's good at many things. He's a good painter. I think films will be very good for him, so I hope they come off. He's great at all things. He's a lovely dancer." -- Maureen Starkey, wife of Richard Starkey, quoted in The Beatles by Hunter Davies (1968).
--"Ringo. He's cute. It's the only way to describe him." -- Mary "Aunt Mimi" Smith, John Lennon's aunt, said in 1964.(quoted in The Beatles in New Zealand(1993))
--"He has become an excellent Beatle and a devoted friend. He is warm and dry witted, a good drummer and I like him enormously. He is a very uncomplicated, very nice young man." -- Brian Epstein in A Cellar Full of Noise(1964)
--"We were all supposed to be something different. Paul was the face, I was the smart one, George with all his mysticism, was the spirit, and Ringo was the heart. I certainly don't have any hard feelings about him, never had a reason to." -- John Lennon
--"Ringo will always be my friend. -- George Harrison, Rolling Stone magazine (Oct. 1987)
--"We asked Ringo to go and talk to him (Paul) because ... Ringo had not taken sides, or anything like that , and he had been straight about it, and we thought Ringo would be able to talk fairly to Paul. I mean if Ringo agreed that it was unfair, then it was unfair." -- John Lennon in Lennon Remembers.
--"Ringo was simply the best drummer in Liverpool. Ringo also had native wit. He didn't know when he was being funny. Ringo Talked in titles. We had to follow him around with a notebook and pencil. You never know what he would say next." -- Paul McCartney, Off The Record (1988)
--"Ringo listened very carefully to what was happening on any song in progress. ... He was critical, in the same way that I could be critical of what the others were doing and not afraid to voice that criticism. He would suddenly say to John, "John, that's crap," whereupon John would look up over his glasses and murmur, "Oh really," and change it. Either that, or he'd make a rude remark back and then change whatever it was the Ringo had picked up on. Paul also took a great deal of notice of what Ringo said. He was a very effective guide, musically speaking; he had a good ear. Although he might not have always had that much to do, you could never forget that he was a major part of the group." -- George Martin, Summer of Love (1994)
--"The tradition that Ringo always had a song to sing on an album was nothing to do with the others being kind to him. ... Ringo occupied a special place in the hearts of many Beatles fans. The most common adjectives you heard about him were "cute and cuddly." Having him sing something on every album was extremely good marketing -- simple as that." -- George Martin, Summer of Love (1994)
--"It is inescapable that Ringo was the catalyst for the others. He certainly completed the jigsaw and The Beatles, with Ringo, became a magnet for the great camera artists of the world, a target for the jaded, lately hostile eyes of people who had hardly known that popular music existed." -- Brian Epstein, Cellar Full of Noise.
--"Playing without Ringo is like driving a car on three wheels." -- George Harrison (1964).
I got a little carried away...but they're really all great and so is Ringo!
