Great piece of rock trivia: Blues Image's ("Ride Captain Ride") lead singer became lead singer for Iron Butterfly.
The guy who sang "Mr. Bass Man" as Johnny Cymbal, became Derek for a song called "Cinammon. "The American Breed" of "Bend Me, Shape Me", became "Rufus". Tony Girasi, who sang "Time Won't Let Me" with the "Outsiders", sang "Precious and Few" in a band called "Climax" [may have been the same band, different name]
