The band who made monumental music achievements with their amps that go to the rockin' number 11, is now reuniting to help save the world and fight climate change. Last the cinema world saw them, Nigel Tufnel, David St. Hubbins and Derek Smalls were Catching Up with Marty DiBergi seven years ago. Since then, it appears that Nigel has been raising miniature race horses but can't find jockeys small enough to ride them, David's busy as a hip-hop producer/colon clinic head and Derek has been in rehab for his Internet addiction. Now they're re-teaming for a concert in London and a new short film that helped open up the Tribeca Film Fest, in a gala hosted by Al Gore.

Rob Reiner's new short is called, simply, Spinal Tap, and is part of a campaign called SOS/Live Earth. The new flick has DiBergi taking credit for the term "global warming," and the band discussing their dedication to charity work, which of course, includes campaigns to help ferrets by raising money to get them Caesar Salad. As if that wasn't enough for hard-core mockumentary and Tap fans, the group has a new single called Warmer Than Hell, which includes the lyrics: "The devil went to Devon, it felt like the fourth degree / He said, 'It it hot in here, or is it only me?'" Luckily, for all of us who aren't in Tribeca, we can see the film along with 8 others here starting today. And for you lucky buggers in London, Spinal Tap will perform in Wembley Stadium as part of the Live Earth concerts this July.

Note: Look for Cinematical's extensive coverage of the Tribeca Film Festival to begin real soon.
