The band are in the studio recording Fallen - the follow-up to 2013's No More Hell To Pay. But Sweet has asked his Facebook followers how they would feel if he was to take a back seat on live vocal duties in the future.

He says: "So I can't hit all the high notes like I used to. I try and choose my battles but unfortunately, gravity has taken its toll. How would it go over if we found some young lad who can hit all the high notes and I just play guitar and sing from time to time? Don't go crazy, just wanted to ask out of curiosity."
