Paranoia and Mr. Limousine Driver were my personal faves. Mark Farner was a guitar hero, then he decided to play keyboards (bad move).
IIRC, Mr. Limousine Driver was when they were Mark Don and Terry (Knight).
Mark's KBs on Footstompin' Music were pretty good. But they brought Craig on and pretty much killed the great old-fashioned 3-man band sound that made them so unique.
Man could Mark kick a$$ on the guitar -- the Marathon cuts on Caught In The Act should have put him up there with Hendrix and Trower.
