@panzade,
Back in the day, though, a Beatles "B side" sold better than many groups' "A sides." I can't say that i recall that clearly, but i think that one was reasonably popular.
I watched the induction into the R & R Hall of Fame speech given by Mick Jagger yesterday (watched it yesterday, it was given in 1988). Mick was kind of snarky, kind of snide, but he was honest, too. He said that there just was nothing going on musically in England at the time, and that no one's prospects were good. Then this band from Liverpool--
Liverpool, fer Chrissake--comes along and blows it all wide open. He then acknowledged that the Beatles "opened" up the North American market for them all. He just couldn't resist getting his little digs in.
Then i watched "acceptance" speech by Richard and George. Richard was his usual, irreverent, "this is all bollocks" self. At one point, he says something to the effect of "Rock and roll? I always thought we were a pop group." Personally, i'd say they were in a category all their own.
