A little trivia via the History Channel:
Only two years removed from a disastrous 1982 world tour that not only failed to turn the album Smell The Glove into a comeback hit, but also led to the group's breakup, Spinal Tap now had to suffer the indignity of seeing the Marty DiBergi-helmed behind-the-scenes film of that tour gain widespread theatrical release. Would the numerous embarrassments catalogued in the hard-hitting rockumentary This Is Spinal Tap provoke public sympathy for and renewed interest in the band that Nigel Tufnel, David St. Hubbins and Derek Smalls began back in 1964 as The Originals? Or would the group behind such familiar classic-rock hits as "Give Me Some Money" and "Tonight I'm Gonna Rock You Tonight" be consigned once and for all to obscurity? In this atmosphere of uncertainty, Spinal Tap elected to go back to their roots, kicking off a tour of small American rock clubs with an appearance at New York City's legendary CBGB's on May 6, 1984.
