I'm 63 and I watched American Bandstand. All of the musical guests would lip sync their songs. The show later became more slick and contrived with proffesional dancers appearing on the weekly saturday show. Dick Clark was a shrewed, hugely successful show business entrapenurial giant. I remember he was involved in the Payola scandal in the 50's. He knew about the business end, promotion and money. I'm not sure if he understood or felt the music that so many of us used to escape into.
Music historians tell us how the manufactored music and performers in the limelight of the early 60's was leaving a hunger for real music and gave The British rockers a shot to provide true Rythum and Blues. It was the British that saved American Rock and Roll.
Slick promoters were pushing performers like Fabian and Frankie Avalon to the top with music that left a lot to be desired. The Beatles, Rolling Stones, Animals and the multitudes of British perfomers was covering songs of the likes of Muddy Waters, Robert Johnson, Carl Perkins, Chuck Berry and so on.
I'm paraphrasing a radio program I'd listened to years ago about the evolution of Rock and Roll.
