Terry Melcher was one lucky son of a gun. He had lived in that house with his girlfriend, Candace Bergen and Mark Lindsay (Paul Revere & the Raiders).
I worked for Mark a few times and he said that Charlie showed up to a few parties there.
Then, Candace broke it off with Terry, so they moved out. Charlie was not informed of this when he sent his gang there.
Apparently, Charlie lacked “Carnal Knowledge” concerning Candace. Ann Margret was in that movie too.
