You Are What You Eat (1968) is a strange, psychedelic and convoluted film as incoherent as its hippy brethren 200 Motels (1971) and Rainbow Bridge (1972). It belongs with that small collection of movies in which more people own the soundtrack than have actually seen the film. The soundtrack is phenomenal. The bright yellow cover is as eccentric as the vinyl itself that features audio cut-ups, squealing Moog synthesizers, relentless psychedelic improvisations, lounge music, Tiny Tim oddities, and the final appearance of The Hawks before they changed their name to The Band.

The list of those involved with the film is an incredible roster of counter culture heroes and weirdos. Tiny Tim, The Electric Flag, Frank Zappa, Peter Yarrow, Paul Butterfield, Super Spade, David Crosby, Hamsa El Din, Barry McGuire, the radio personality Rosko and several others.
