The masked rockers were forced to postpone the first two weeks of a planned North American tour with Marilyn Manson to allow the singer to fully recover from an "unplanned" operation, but now Taylor has informed fans he has been given the OK to get back onstage - as long as he doesn't over exert himself.

In a tweeted update, he reveals his doctor told him to ease his way back into live shows, urging him to promise there will be "no headbanging" or "jumping" for him.

Corey adds: "But I'll sing my a** off."

He expects to be "back to 90 percent" within the next four to six months, and "100 percent" in a year.
