McCartney Times

Conservative parents of the 1960s, who grew desperately concerned with the developing counterculture era, would have quietly hoped that the breakup of The Beatles at the end of the decade would have quietened the resistance and brought peace back to the ordered world.But instead, the 1970s arrived and took music into even more experimental realms, making it undoubtedly the greatest decade for music.
