THE 1960s was an era of isms du jour. Race riots, war protests, space race, Nam, alternative lifestyles, bra and draftcards being barbequed…we circled the moon and no one wrote a song about it. Society was spinning counter-clockwise. And so was danceable music. The top album artists of the1960s were The Beatles, Bob Dylan, Monkees, Elvis, Simon & Garfinkle and The Doors. Beach Music was on life support. So why did it survive?
