When They Might Be Giants suggested the band reunite with The A.V. Club during a Chicago tour stop, they didn't just want to do a live version of "Tubthumping." No, they wanted to go beyond that. The idea: Get a whole bunch of guitars and perform America's "Horse With No Name." It's simple two-chord song, easy enough for just about anyone to play. So we rounded up as many acoustic guitars as we could find and took the stage at the Vic Theatre in Chicago.
