In addition to appearing together at the event, Bono, the Edge and Jay have teamed up with Swizz Beatz to record an as-yet-untitled song produced by Beatz that will be available on iTunes.

"Last night we wrote a song. ... Bono got a call from a producer, Swizz. He and Jay-Z wanted to do something for Haiti," The Edge said on Saturday on "The Dave Fanning Show" on Ireland's 2FM.

"So, Bono came up with the phrase on the phone, and last night we were here, we wrote a song -- finished, recorded, and sent it back to them. So that might be the next thing you hear from us!"

Swizz also weighed in on the all-star tune, writing about it on his Twitter account over the weekend. "Me, Bono, Hova have something to say about Haiti. Stay tuned. I told you I was working on something amazing for Haiti. They need us!"
