In the hilarious, pitch-perfect Christopher Guest parody, A Mighty Wind, three 1960s folk bands participate in a reunion concert to memorialize the promoter who brought them to the public eye. Guest and co-writer Eugene Levy burlesque the most celebrated of the folkies. Michael Mc­Kean, Harry Shearer and Guest himself play the Folksmen, whose close harmonies, rambling didactic spiels and affable camp-counselor personalities recall the Kingston Trio.

The New Christy Minstrels return in the form of the New Main Street Singers, a tirelessly upbeat crew that has been reconstituted in the years since its initial break-up. Only one of the original musicians (Paul Dooley) still plays with them; the current roster includes the ex-doper daughter of one of his partners (Parker Posey), and a perky couple (John Michael Higgins and Jane Lynch) who practice a private religion built around the power of color. Best of all are Levy and Catherine O'Hara as Mitch and Mickey, whose partnership and romantic relationship broke up messily (he wound up in a psychiatric hospital). Their music--as well as O'Hara's Maritime accent--brings to mind the Canadian duo Ian and Sylvia, though their album covers are in the style of Peter, Paul and Mary.

Guest has carved out a unique niche for himself with his send-ups of unorthodox pockets of show business. He co-wrote Rob Reiner's This Is Spinal Tap, which chronicled the disintegration of a heavy-metal band. His directorial debut, Waiting for Guffman, was built around a community theatrical group. Best in Show spoofed the Westminster Dog Show.
