This is Spinal tap

England's loudest band. The main members are David St. Hubbins (Guitar and lead vocals), Nigel Tufnel (Lead Guitar), and Derek Smalls (Bass). Rumour has it these guys are actually the American actors/filmakers Michael McKean, Christopher Guest and Harry Shearer (who also plays many characters on The Simpsons) respectively. Best known for their 1984 rockumentary "This Is Spinal Tap", directed by Marty Di Bergi (who, rumour has it, is really the well known film maker Rob Reiner!). Filmed an entertaining sequel in 1992 called "The Return of Spinal Tap" which mostly featured live footage of them playing a gig at the Royal Albert Hall in 1992, plus some interviews.
