Well, I don't know what more can be said about the Beatles. So much has been written about them and will continue to be.
The most remarkable thing about them was their phenomenal success, seemingly unparalleled ever since. They were popular and famous globally. It seemed the entire planet had an extreme case of Beatlemania. Many years later, all things-Beatles sells. The upcoming remasters will probably set new records.
The Beatles were the biggest band but as solo artists none of them really lived up to Beatles potential. Paul McCartney had the most successful post-Beatles career in terms of album sales. He also toured and did zillions of concerts. None of the others can touch him in this respect. Come to think of it, maybe Ringo could. Ringo was always very musically active and performing. He just couldn't write songs to put him on the level of the others.
Re: George, I've always believed him to be largely underrated. But I think he was an important underpinning to the Beatles cohesiveness in the sense of being a buffer and support between John and Paul. He was subservient to them and did what was expected of him. I love his guitar work all around on their records. Some of it simple and repetitive, e.g. "And I love Her," but utterly charming and engaging. Also: "Day Tripper," repetitive but solid and good (or did the studio edit out any errors on that). I mean it's hard to play something over and over without slipping at some point, missing a string or unintentionally muting a fret, right?
George had a limited singing range, but the others knew exactly what songs would work for him. Consider "I only want to dance with you." He does a great job with that tune without straining himself vocally or in having to strive for notes he couldn't reach.
He knew Paul before both of them met John and he was already playing guitar then. I think he was a true guitarist because he was playing when he was very young and must have done so for the pure enjoyment of it. I feel he was a pure musician in the sense that he wasn't aspiring to be in a band in order (cliche) "to meet girls" or to be famous. He could never have imagined how popular the Beatles would be anyway. He played guitar because he was a natural for it. I'll bet he'd be playing guitar today even if he never became famous.
So, this thread could probably go on forever if people start getting going on this subject. Beatles - Beatles - Beatles, an endlessly fascinating band and much food for thought.
Surely, a lot of you guys in bands are puzzling over their fame and wishing you could have a piece of it, if not even more than they did. C'mon - admit it everyone! Aren't you the least bit jealous? I know I am!
