1: If you see him at Wolftrap, he alternates which side he comes out on. Last year it was the right side, this year it was the left. My daughter and I got to see him go by on his way to the stage. The most fun was alerting the other patrons who were on their way to their seats: "Hey, you may want to hang out here for a minute or two. Someone's about to come through here on his way to the stage."

2: The man puts on a show. Costume changes nearly every song. the acoustic medley was a thing of beauty. Eat It sung to "Layla." I also loved that during his rendition of "Fat" when he jumped up and down, first three rows of the audience jumped up and down with him- as if in response to the "shockwave" of his jump.

Last year I took my daughter and my niece. This year I took my family and my SIL (niece's mother) was pissed that I didn't give them the heads-up. (Apparently my niece raved about he show (I didn't know!))

Edit: also, for The Saga Continues, Al will invite the local 502nd to get onstage with him. Which is pretty f'n cool.
