There is no way Loki is passing up a chance to jump up on that stage and do a little entertaining of his own. Especially not with Bartleby around to haul his ass away before he embarrasses himself, the audience, and the entire Kingdom of Heaven.

The volunteer musicians aren't expected to do much more than keep a beat and keep up with Loki, who launches into an enthusiastic rendition of King of Rock (http://www.youtube.com/watch?v=qXzWlPL_TKw). Yes, he even performs both parts. It's a sight to see.
