Battle For The Planet Of They Might Be Giants

Basically just a variation on Battle For The Planet Of The Apes. When the Johns are playing, the audience shouts, "John!" When the Band of Dans is playing, the audience shouts, "Dan!" Other band members are sometimes included as well. One show had Jim O'Connor on the trumpet and Tim Somebody on the trombone, and the audience shouted "Im!" when those two played. There was another show at which Jim played alone during his parts (and won, through sheer force of numbers).
