The WSJ reports:

During the song, each band member intended to make an individual, grand exit across the catwalk. But the Edge took a bad step and fell off the edge of the catwalk on his way out (Bono did his best to keep the show moving, and kept on walking while the crew attended to his bandmate).

The set list:

“The Miracle (of Joey Ramone)”
“Out of Control”
“Vertigo”
“I Will Follow”
“Iris (Hold Me Close)”
