The thing that gets me, there are so many B SIDES being used in commercials now adays that casual listeners won't evern recognize that's a beatles song. I guess Michael Jackson must have some heavy lawyer bills, but still that's impressive. Epstein basicly gave royalites away, Apple records hemoraged money, and still these guys are milionairs for what they've done.
Brian Wilson is a great songwriter, but George Harrison wrote a few hits. How can you compete with a band when the third member is writing hits?
Also, I don't think a band evolved as much from one origanl point to another origanal point as the beatles. Sgt Peppers sounds nothing like Please Please Me and still they never lost thier fan base.
