Rob - I thought Bono's voice was a bit off the first song or two in Cleveland as well, and figured since it was the last of their North American stops maybe he was just strained/tired. By the third or fourth song he was warmed up though and absolutely slayed it, hitting all the notes. Maybe just an off night in Toronto?
I'm with you 100% on Red Hill Mining Town, and I also enjoyed hearing Bad live for the first time (at least that I can remember). Fabulous show!
