He's a good singer but he's not.......different. He'll, no doubt, have a CD out in no time at all, may sing with a few minor opera comapnies and will, eventually, disappear.
I don't know the queen, personally, so I don't know what her tastes are but I do know I'd be bored to death by half the acts that are going to be on the RVP. Me, I'd rather have had someone like the woman who spot-welded her knickers. At least she was a novelty.
