I'm sure they'd love to break into other material,like ANY touring act. But the smart,business sense side tells them to stick to what the majority wants to hear. They gotta play it smart or lose bodies in the crowd at the shows. The minority wants a few different tunes,and unfortunately,that's US music nerds. T
