Oh, notnotnot Graham Norton, please! Whatever he's like on his own show (and I think he's a lot better on that this year), he would be a DISAAAAARRRRSTER on SCD, much to in-your-face and full of himself. He's still too fond of getting cheap and easy laughs at other people's expense.
I think everyone's right about Bruce staying for the 10th anniversary series, though.
Oh, and ITT has been so much better this year, with Zoe.
