On Saturday, Hayden Panetierre appeared onstage alongside her Heroes co-star Greg Grunberg, but it wasn’t to promote their show. Instead, the TV cheerleader rocked out at Cal State Fullerton, singing lead vocals for Greg’s group, Band from TV. As for the other guys on stage, you might recognize them as well. The band includes Desperate Housewives’ James Denton and House’s Hugh Laurie. Now the only question is, do any of them plan to quit their day jobs?
