Record producer from the movie One Trick Pony (1980). In a nice piece of casting against type, minimalist rocker Lou Reed plays this producer who loads up the latest Jonah Levin single with strings, horns, chorus girls, and all other kindsa crap (so, basically, Phil Spector).
Folk rocker Paul Simon plays Jonah Levin-- basically himself, if he had never made it big.
The movie also features Harry Shearer as Levin's manager, Rip Torn as his studio head.
Playing themselves in the film are real musicians Tiny Tim, Sam & Dave, the Lovin' Spoonful, The B-52's, and David Sanborn.
