I didn't like his shows, but he seemed to be a nice guy and he gave some musicians a shot, even if they were forced to lip-synch to pre-recorded tracks. Lots of TV was that way back then, even the really big shows, so he would have been swimming against the tide to force anything else.
I'm surprised no one has posted his most memorable words:
“Music is the soundtrack of our lives.”
― Dick Clark
I heard him say this in a TV interview many years ago, and I was struck by how apt it was. We associate periods of our lives extremely closely with whatever music was surrounding us at the time. That music later becomes a mnemonic, reminding us of those earlier times when we re-encounter it.
