U2 lead singer Bono back in action post injury

New York: U2 lead singer Bono is stronger than ever following an injury, said band mate.

"Bono is back in form. His back injury unfortunately forced us to postpone dates on the US tour, but we are performing again, and he is in great shape,” a new daily quoted the guitarist as saying during the Denise Rich Angel Foundation Ball at Cipriani Wall Street.

"We’re working on a new album that could be out early next year," he added.

Bono had slipped a disc in his back that punctured a ligament and broke into two pieces.
