On Monday for World AIDS Day, U2 put on a surprise concert in New York's Times Square.

Because Bono was unable to perform with the band due to his recovery from a bicycling injury and surgery, Bruce Springsteen and Coldplay's Chris Martin stood in and handled the singing duties.

Springsteen sang the iconic "Where The Streets Have No Name" from 1987's "The Joshua Tree" album for the A (Red) Thank You Concert, presented by Bank of America.

Skip to the 37-minute, 20-second mark of the video to hear how it sounded. Or, just check out the concert in its entirety.
