Niall Stokes of Hot Press reviews U2’s BBC1 gig on the Hot Press website and quotes Bono telling Radio 1 DJ Jo Whiley: “We fucked it up a couple of times, but I think we got away with it.”

Stokes also mentions a conversation with The Edge in which the guitarist explains to him he has as a new trick up his sleeve:

“Across the other side of the room, Edge is beaming – clearly satisfied that a good night’s work has been done. I compliment him on his slide playing. “We’ve had to invent a new thing,” he tells me, “so I can switch from normal chords to playing slide in the middle of a song. It’s tiny, and fits on the tip of the finger. I’ll show you…””

Unfortunately, Stokes does not elaborate on Edge’s thingie.
