Ringo fit. Period. He helped to make the proverbial sum of the parts as special and unique as can be, and um, the best band ever. Put John Bonham or Keith Moon's style in your head, and put it into any Beatle's song. Doesn't work. I'm listening to 'Love Me Do' with Keith on drums right now and having a laugh (sorry folks). Ringo completed the group, did a good workingman's job of drumming, offended no one, and in alot of ways, was the glue, especially towards the terse end of their days. He's no Keith Moon, John Bonham, Neil Peart, Buddy Rich--whatever, but he didn't need to be either.
