Bono makes his third consecutive appearance on Jimmy Kimmel Live!'s (RED) Shopathon -- an hour-long fund raiser for the fight against AIDS. He duets with Pharrell on a lounge-style version of "Stayin' Alive," accompanied only by a piano. In the final chorus, the two change the words to "saving a life / (RED) is saving a life." Later in the show, Bono joins the all-star cast to sing the tongue-in-cheek song, "We're Going To Hell," that's been sung the previous two years, as well.
