I get your point. I don't know whether it's really warm in Sydney or whatever, but he seemed REALLY puffed and couldn't finish a few lines to the songs. Maybe he was running around too much (although he did that at the concert and had no problems). Plus at the end of one of the songs (don't remember which one) he just collapsed on the floor, unable to finish the line.
Anyway - it was great! Looking forward to music/video/youtube uploads!
