Spinal Tap Reunites for Live Earth To Fight Global Warming

Director Rob Reiner spoke to The Associated Press on Tuesday to explain the reunion of Spinal Tap -- a band always known more as a parody of rock 'n' roll excess than environmental awareness.

"They're not that environmentally conscious, but they've heard of global warming," said Reiner, whose other films include "When Harry Met Sally" and "Stand By Me." "Nigel thought it was just because he was wearing too much clothing -- that if he just took his jacket off it would be cooler."
