. He had a long, successful career in the music industry, with his most widely known contribution probably being the epic organ intro to Bob Dylan's "Like a Rolling Stone

The Golden Chords had been put together to exploit the short-lived gospel music craze that popped up around Los Angeles in the early '60s. They covered "Wake Me, Shake Me" on a live album called Introducing The Sweet Chariot
Kooper listened to that album and was inspired to cover "Wake Me, Shake Me" with The Blues Project. He considers it the group's signature song. They often closed their shows with long, improvised versions of it.
