The exception that proves the rule for me is, of course, James Blunt. He makes me ashamed to be British and his refusal to let Weird Al Jankovic release his 'You're Pitiful' parody merely confirms that he's a prick of quite monumental preciousness.
So lets try this. I loathe Robbie Williams with a vengeance but 'South Of The Border' is a good one. Cliff Richard is a boil on the backside of humanity and his material is so sickly sweet that your teeth rot just listening to him. But 'Devil Woman' rocks!
I dunno, the theory works for me!
