I remember seeing the live feed of this...oh my goodness, it was GREAT!
I didn't check out the video that linked to in this thread (since I've already seen it), so I'm not sure whether it was cut out or left in, but Danny said he (may) be busting out that trick when jamming at conventions--just so y'all know.
I think it would be pretty easy for anybody to do a story like that. He did say that the rest of it was pretty much improve and the only sure fire thing was the Jack and 645 part.
