This is how you make an exit from a filled ballroom: Bono sang a bunch of U2 songs with Nile Rodgers and Chic on Friday night at the Hammerstein Ballroom in New York. The occasion was Rogers’ and Nancy Hunt’s annual We Are Family Foundation dinner. The night was a huge hit with an appearance by former President Jimmy Carter as well. When Bono launched into “Mysterious Ways,” he also launched into the audience, as you’ll see. His disappeared for a couple of seconds, but security followed. He popped up at the back of the theater, finished the song, and made a magical exit. Very cool. Chic went on with a Studio 54 rave of hits with Kathy Sledge.
