In case you missed it the other day, U2 announced a contest to attend a dress rehearsal and meet the band, all in support of the (Red) campaign. You can see that piece here.
Bono appeared on a special edition of Jimmy Kimmel in support of a number of efforts to raise money to eliminate Aids in Africa. For those U2 fans who remember, a character Bono donned during the ZooTV tour way back when was named MacPhisto. A devil resplendent in a gold suit and red lamé. Well, the character made his return, of sorts.
