It probably doesn't count, because you guys mostly mention James interacting with the audience, not actual rhythm modifications or whatever. But if I could take the vocal melodies of The Killing Hand from Live at the Marquee and replace it with the original album's as the standard for this song, including all the WOAAH's and the crazy screams in the song's grand finale, I would've been a happy man.
Also, the high notes James throws in Under a Glass Moon in the current tour. Hearing him screaming out "Praying for TIME to disappear" like that is either awesome or amusing every single time, which is enjoyable either way.
