Fresh from his yak-toting cameo in Head, Frank Zappa made this gorggy orgy of groupies, frogs and horses, and suddenly the Monkees film looks like Chariots of Fire in comparison. Filming at Pinewood (next door to 2001) in little over a week, Zappa used video cameras to cut costs and flood every frame with multiple Chromakeyed images, queasy colour saturations and restless fuzziness in general, in what starts out as a satire on a typical rock tour of America but quickly descends into a headache-inducing kaleidoscope soup. Keith Moon plays a nun. Ringo Starr plays Zappa. Ringo’s chauffeur stands in for Wilfrid Brambell.
