I had to do this one: Blueman Group:
This went down with the same people but minus Tracy when I saw them in Vegas. One of the best concerts I ever saw in my life! One major party! The audience actually sung Baba O'Riley and they did Jefferson Airplane's "Somebody To Love" as well with some of the audience singing at the top of their lungs nailing it down! (I was one).
I forgot about this. Here's some of the show I was at!
This wasn't the show I was at, but it was the same people and this was done. Yes, we got up and played along. I was approached with the camera, but refused to let them do that to me, so they went with someone else. (The price I paid for being in the third row!)
One of the greatest bits ever! (Wish they did this in Vegas when I went).
