Spinal Tap are back!

Apparently they are joining in on the Live Earth concerts on July 7th at Wembley Stadium. All the original members will be on board: guitarist Nigel Tufnel (played by Christopher Guest), singer David St Hubbins (Michael McKean) and bassist Derek Smalls (Harry Shearer).

They will also be releasing a single - Warmer then Hell - and a new 15 minute film directed by Reiner on the band's reunion will also play at the Tribeca Film Festival in New York.

Reiner said of Spinal Tap's reunion: "They're not that environmentally conscious, but they've heard of global warming.

"Nigel thought it was just because he was wearing too much clothing -- that if he just took his jacket off it would be cooler."

"What I think is going to be nice about this whole effort is there will be marching orders for people.
