Spinal Tap just finished a dynamic set that included the song "Stonehendge" featuring the band's patented midget-sized replica of the ancient wonder. The band also premiered its hot new tune, "Warmer Than Hell," which was created specifically for Live Earth. Spinal Tap capped off their Live Earth appearance by inviting "every bass player in the known universe" to join the onstage for their last song "Big Bottom". Bassists from many of bands on the Live Earth line-up, including the Foo Fighters, David Grey, Block Party, James Blunt and the Beastie Boys took part in the epic jamfest.
