Metal relics Spinal Tap caterwaul and bicker their way across America to promote new album Smell The Glove, followed at every grunt and gurn by megaphone beard Marty DiBergi (Rob Reiner). Less fly on the wall, more Spanish fly on the crotch, it's the spandex-clad mockumentary that helped finally consign heavy rock to the realms of zero credibility.

DVD Extras:

Commentary from the band, more than an hour of deleted scenes, theatrical trailers, three TV spots, four music videos, product endorsement ads, Catching Up With Marty DiBergi interview, rare TV appearance on the Joe Franklin Show, Flower People press conference.The main menu carries a commentary from the band. The subtitle menu carries a commentary from the band. And number 11on Scene Selection is... Go on, guess. That's the welcome intelligence which runs hard through this disc like a cucumber slung down a bass player's pants. The extras are less an odds 'n' sods lucky dip, more a loose companion movie which furthers the band's back story (Smalls' divorce negotiations, Tufnel's unseen replacement, St Hubbins' New Romantic son...). Then there's the commentary, as the band poke fun at all-comers (DiBergi and his face fuzz: "I know it's fake, you can see the little bits of white glue on it"), update us on characters (one of the Stonehenge dwarves is now in sales) and declare that everyone else, including Elvis, is now dead. A belter of a disc that's as fundamental to your DVD enjoyment as paying the leccy bill.
