Editor's note: So, OK, this isn't the biggest news of the week, but when I saw Steve Caratzas's post about Spinal Tap reuniting for the Live Earth concert, I just had to have it for our post swap… must be my coming of age in the 80s…

Stop the presses! In the biggest environmental news since Bill Hobbs pulled his Norma Rae routine with the nation’s napkin workers, Spinal Tap will reunite for a performance at London’s Wembley Stadium as part of the Live Earth concerts scheduled worldwide for July 7.

As everyone (but Bill and his gang of Sheryl Crow bashers, presumably) knows, Spinal Tap is a mock heavy metal group immortalized in the 1984 mockumentary, This is Spinal Tap, directed by Rob Reiner. Original members David St. Hubbins ( vocals, guitar), Nigel Tufnel (lead guitar), and Derek Smalls (bass) will all be back to help save the world from global warming. It is unclear who the unlucky drummer will be.

A new 15-minute film directed by Reiner on the band’s reunion will also play at the opening night of the Tribeca Film Festival in New York on Wednesday. The slate for the opening gala, to be hosted by Al Gore, was previously announced, excepting the Reiner short.

Opening the festival will be a screening of several global warming-themed short films, all produced by the SOS (Save Our Selves) campaign. SOS is organizing the Live Earth concerts, set to be held across seven continents.

“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.”

This is but the latest of several reunions for Spinal Tap, whose last album was 1992’s Break like the Wind. For this auspicious occasion they have produced a new single entitled “Warmer Than Hell.”
