I'm sure Prince William couldn't care less whether they think he's got talent in singing or not.
As for others saying he's got talent, they aint exactly gonna say he sounds like a cat being dragged backwards down some stairs are they?
For the record, John Bon Jovi sounded rubbish too on that occasion and I know full well that he can sing live, must've been an off day for both him and Taylor Swift who I also can sing well.
Finally, you're a little ray of sunshine aren't you weecalf? LOL Is there anything or anyone you do actually like?
