Spinal Tap to warm up the crowd at eco-friendly Live Earth gig

SPINAL TAP is back, and this time the US mockumentary band wants to help save the world from global warming.

The mock heavy metal group immortalised in the 1984 parody movie This is Spinal Tap will reunite for a performance at Wembley Stadium in London as part of the Live Earth concerts scheduled worldwide for July 7.

The original members of Spinal Tap will be there: guitarist Nigel Tufnel (played by Christopher Guest), singer David St Hubbins (Michael McKean) and bassist Derek Smalls (Harry Shearer). Rob Reiner, who both directed This is Spinal Tap and played the fake documentary maker Marty DeBergi in the film, will also be in attendance.
