Legendary mock rock band Spinal Tap reunited for the Live Earth benefit concert on Saturday, and this clip shows them performing the song “Big Bottom” with an army of bass players. Leave it to Spinal Tap to come up with something like this.

The band brought out bass players from almost every other band that played the Live Earth show, and even a few members that were not bass players such as Metallica’s James Hetfield and all of the Beastie Boys.

They also performed a song they wrote just for Live Earth, entitled “Warmer Than Hell”. It was about the devil himself coming to Great Britain and complaining about the heat.

I wish these guys would come out with more new stuff. They are true rock and roll originals who know how to make people laugh.
