Just performed Mosh, holding up a simple handwritten sign at the end with the word "VOTE." The audience was ecstatic from what I could tell, but hey, it's a TV crowd.
The song, for me, is much stronger with the animation but having him sing it live(?) on national TV just before the election adds to its effect as a GOTV effort.
Have folks been watching the rest of the show? Have they played off the Mosh video in other segments?
