If you think those three songs are three of the stronger songs on Pepper, then I think you miss the point of Beatle music. So here we go with what I think of Pepper's tracks: I think that if you think that, then you really don't know how to agree to disagree. Obviously the whole board must not know the point of Beatles music since you've gotten a dozen people to disagree with you
Sgt Pepper's LHCB: A good opener, but nothing special about the song. I love the mono version's more up-front guitar. I love Paul's voice in this, for one -- that's something it has going for it. And you're right, it is a good opener, but maybe it IS a filler since it is pretty essential in the album. I do, however, enjoy it as much as, say, It Won't Be Long, I don't consider IWBL filler.
With A Little Help: A wonderful track, setting a good mood. Perfect vehicle for Ringo. Yes.
Lucy: All-time Beatle masterpiece, and it can still send shivers up my spine. Thanks to Paul for suggesting to John how best to sing it (elide the words, dreamily). Mono version sounds better for me. Lucy in the Sky with Diamonds doesn't do it for me like the other songs in this album, if you know what I mean. I like it, but it never quite moved me, perhaps because I may have had to have been alive and experience this when it first came out to know where you're coming from. But since I don't, I do not consider this a masterpiece as much as I consider it a solid Lennon song.
Getting Better: A filler, but good filler (as I said before). Saved brilliantly by John's "It can't get no worse" and "I used to be cruel to my woman ....etc etc" pieces. Like others have said, just because he repeats "Getting Better" a lot, it does not make it filler. It's a very enjoyable song, but like you said, you must like it to to call it GOOD filler. I just don't think that's the case.
Fixing A Hole: I regard this as Paul's only psychedelic track - ever - and it's a good one. Love the lead guitar. I'll refer you to Indica's comments.
She's Leaving Home: A middle-class story about a middle-class rebel. Saved by John's contributions to the chorus ("we didn't know it was wrong", "fun is the one thing ...." etc) You also said in another thread that the song was too linear. First off, I do agree that I adored John's singing in this, but the Beatles were a TEAM. They wrote a LOT of songs together, and this is an example of how they acted as a team -- Lennon's voice was obviously the best for this part. They could have easily put Paul's vocals in twice, but he doesn't have that voice to do the part, just like it wouldn't make sense for Harrison to sing Octopus' Garden.
A team effort, and one of my favorite songs to listen to. My science teacher from back in 5th grade, for instance, said this song was one of her favorites to listen to growing up, and I don't think filler would have that kind of effect. I also don't understand this "linear" argument... the song is supposed to be a story. Why should every song have that Eleanor Rigby touch to it by using a story as a vehicle for driving a point? The fact that it ISN'T immitating that masterpiece is great, as Paul is not using the same formula as before.
Mr Kite: Nice psychedelia. Heavy-sounding lyrics, great creation of atmosphere. Yes, but this ISN'T filler? Mr. Kite is very nice, but isn't as nice as She's Leaving Home, 64, or Rita.
Within You Without You: I know I'm in a minority, but I think this is another all-time Beatle masterpiece. This is a densely-packed five minutes of music played on a variety of east-and-west instruments that beseech and plead through words that are ... well, wise words. I never was too big of a fan of this piece, so I'll refrain from saying anythign about it.
64: Did someone wedge this ditty after Within You to show up Paul's emptiness? Wouldn't surprise me! The funnest song to listen to in this album, When I'm 64 is NOT filler. It's fun to sing, fun to play, fun to listen to, and one of the best on the album.
Rita: A very cool song in the way it's played. But the lyrics ... it's filler (but good, as I said before) I don't really care if the lyrics aren't like Yesterday or Eleanor Rigby or For No One... this song relies on alliteration and consonance, and is excuted brilliantly. Well done, Paul!
Good Morning: A bustling, busy, back-in-time, forward-in-time classic. Not a classic IMHO. Definitely not much better than any of the other "good fillers" you mentioned
SPLHCB reprise: Kind of cute, but well done. On ya Paulie. Agreed.
A Day In The Life: One of the great Beatle maserpieces, maybe their greatest. Still get the goosebumps as John gently sings "I read the news today, oh boy" Yes, but you could say PAUL saved this. John couldn't think of the middle-eight, so Paul made up the "Woke up, got out of bed" part. It was kinda needed, because it was something different from what John was singing, and John and Paul worked as a team, because as soon as Paul uttered the lyrics "Somebody spoke and I went into a dream," John chimes in with that "ahhhh" part. If Paul didn't do that, it wouldn't have the same effect.
The argument can be played two ways.
