Blimey!!
I'm a child of the 60s. I was 16 in 1965. Slap in the middle of it all., so you'd expect me to know the Beatles.
But whatever your age it's almost negligent to not be at least vagueley familiar with the Beatles/Stones/Beach Boys and the other major bands of the period. But the thing is, I'm also not ignorant of what went before them, from the 50s Rock and Roll, Doo-Wop etc,..to the stuff before that, such as vocal groups like the Ink Spots and Mills Bros, the swing bands of Miller, the Dorseys etc. great band singers such as Helen Forrest, Edythe Wright, Billie Holiday, Dinah Washington, Keely Smith and the earlier jazz stuff by Armstrong, Ellington, etc. This is all great music.
Don't waste it!!
