A couple of future enemies of the state. First, John Lydon aka Johnny Rotten: Neil Megson, aka Genesis P-Orridge of TG and Psychic TV:
Can I make a polite request that names are put below the photo and not above, it makes it very difficult to have a guess at who these are when we see the name before we see the photo!
Mercury refused to have his overbite corrected for the duration of his life because he was concerned about the effect it would have on his singing voice. (this was not without cause. and besides, what's Freddie Mercury without his giant front teeth?)
It looked less protrusive when he was in Queen, his face must have grown bigger. I think I read somewhere Barbara Streisand wouldn't get her big nose fixed for the same reason.
Poor bugger also went to British boarding schools. Those gnashers must have been a giant red bullseye to the bullies.
He knew it wouldn't affect his singing. If you see the video he is clearly joking when he says "my dear i wont be able to sing if i fix my teeth".
a marked change in voice is a common auxiliary effect of orthognathic surgery--especially in severe cases like Mercury's. and there are a lot of sources that indicate that he was very aware of this, his having joked about it notwithstanding.
The poor guy's already in a Catholic girl's school, and then they make him wear a funny hat. No wonder he was on a highway to hell.
