New York, June 27 (AP): In a frank and heartfelt speech, U2 bassist Adam Clayton thanked his bandmates of four decades for their support during his treatment and recovery for alcohol abuse years ago, and then joined them for a rollicking rendition of a few hits.

"We have a pact with each other," said Clayton, 57, who was receiving an award from MusiCares, the charity arm of the National Academy of Recording Arts and Sciences. "In our band, no one will be a casualty. We all come home, or none of us come home. No one will be left behind. Thank you for honouring that promise, and letting me be in your band."

He ended by quoting lyrics that Bono, U2's frontman, had written when the band was starting out: "If you walk away, walk away, I will follow." At that, his bandmates came out to join him, performing Stuck in a Moment You Can't Get Out Of, Vertigo and, fittingly, I Will Follow.

The evening at the PlayStation Theatre in Times Square also featured performances by rapper Michael Franti, Jack Garratt, reggae singer Chronixx, Macy Gray, and The Lumineers, who are currently appearing with U2 on their "Joshua Tree" tour.

Clayton was introduced by British record producer Chris Blackwell as someone who "lived through addiction and came out the other side, and has been courageous enough to admit it".

Taking the stage, the bassist quipped: "I'm not used to achieving anything on my own." Turning serious, he said: "I'm an alcoholic, addict, but in some ways that devastating disease is what drove me towards this wonderful life I now have. It's just that I couldn't take my friend alcohol."
