David St. Hubbins and Nigel Tufnel have been friends since they performed as children outside London's tube stations. Working under a succession of names, they eventually found success in 1967 as Spinal Tap. Within a year, their singles were climbing the charts. The band expanded and in 1983, armed with a new record label, they returned to America after an absence of six years. They were greeted by film director Marty Di Bergi -- a Spinal Tap fan for sixteen years. This is the film he made of their tour into the American heartland.
It stays so wickedly close to the subject that it is very nearly indistinguishable from the real thing. -- Janet Maslin, THE NEW YORK TIMES
