Shep Gordon is a swashbucklingly garrulous but now placidly retired manager-cum-agent who built a lucrative career launching Alice Cooper to superstardom and had an association with many huge names along the way, including Sylvester Stallone and Groucho Marx. He is a legend in the industry, not much known outside it; Mike Myers came across Gordon's badass negotiating style when he was arranging for Alice Cooper's cameo in the first Wayne's World film, and now evidently hero-worships this king of a thousand raucous anecdotes, in the same wide-eyed way that he admired New Age author Deepak Chopra, inspiration for the comedy The Love Guru.

Anyway: this documentary homage to Gordon is Myers's feature-directing debut and it makes for a lively, entertaining guide to the LA music scene in the 70s and 80s and the film business – Gordon dabbled in movie production. But it's a little dewy-eyed about Gordon himself, whose sexual politics in those hell-raising, hair-raising days were perhaps not as adorable as Myers assumes.
