An intimate crowd of 250 was the receiving end of a special surprise performance by Irish band U2's Bono and The Edge.
The charity fundraiser event where four of the band's songs were performed was for Mencap, which is an organization centered on getting equal rights for people with learning disabilities.
London's Union Chapel was the venue for the event, a far cry from the sold out stadium concerts that the band usually play.
The temporary duo performed as a warm-up act for Scottish rock group Biffy Clyro. They performed their songs, "Stay," "Desire," "Angel Of Harlem" and "Wave Of Sorrow."
U2 frontman joked about his fellow bandmates. He says, "Don't tell Larry (Mullen) and Adam (Clayton) we've done this."
