Crank it up to 11, baby, because Spinal Tap is reuniting for a performance this summer at Wembley Stadium in London as part of the Live Earth concerts scheduled for July 7th.

And as if that wasn’t enough to get you excited (what are you people, made of stone?), there’s also a new 15-minute short film, directed by Rob “Marty DeBergi” Reiner, documenting the reunion. It will be making its debut at the Tribeca Film Festival this week in NYC, but if there is a music god, start praying that it will be available to the masses…and soon.

Reiner said the new film explains what the band has been doing since the last time we saw them:

“Nigel has been raising miniature horses to race, but can’t find jockeys small enough to ride them; David is now a hip-hop producer who also runs a colonic clinic; and Derek is in rehab for addiction to the Internet.”

The Live Earth concerts are being held to save the world from global warming, and Reiner acknowledged the band didn’t know much about the cause:

“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.”

Sigh…I’ve missed them so.

The cause has also spurred the band into recording a new “Warmer than Hell,” with lyrics including:

“The devil went to Devon, it felt like the fourth degree/ He said, `Is it hot in here, or is it only me?”‘
