I saw the tail end of it last night and that's the only time I've ever watched it. Simon Cowell told some crooner/poseur that "He ought to GIVE UP and find something else to do"
The late Tommy Vance - who had a talent spot on his radio show - used to tell losing contestants: "DON'T give up"!
What a contrast!!!
It's bad advice that Mr Cowell gives to his contestants. Even if they can't sing for toffee, what harm are they doing' and why shouldn't they massage their own egos? They can find their own level and perhaps work as karaoke hosts or singers at Working Mens Clubs.
Having said that though, the X Factor is merely 60 minutes of entertainment, and part of that entertainment is Simon Cowell's put downs.
