Rick Allen, the iconic drummer of Def Leppard, is opening up about his recovery journey only months after he was assaulted after a show in Fort Lauderdale in March.

The 59-year-old drummer sat down with “Good Morning America” in an exclusive interview to talk about the attack, where the drummer said he was “totally blindsided.”

“I heard a couple of steps and then I just saw this [flash] and the next thing I knew was I was on the ground,” said Allen. “I landed on my backside… hit my head on the pavement.”

Allen, who lost his left arm in a car crash in 1984, said he feared he would be attacked again, so he reached his hand up in the air and said, “I am no threat to you.”
