The Beatles' 'Message'

I've always felt that The Beatles were about a lot more than just the music. They were a social phenomenon. They also had energy and optimism that we Baby-Boomers loved. These two quotes are great examples of their 'message':

"If The Beatles or the 60's had a message, it was 'Learn to swim. And once you've learned - swim!" - John Lennon

"It wasn't so much that we foresaw a big success. We just never thought that anything particularly bad would happen to us. We never felt... never sat down at one particular point at all and, sort of, worried about anything. We've always thought that something would turn up sometime." -Paul McCartney
