You've got to hand it to Tubridy and co - they're really giving it socks in terms of trying to get decent Late Late Show guests this time around and tonight is absolutely no exception.

We already knew that Will Ferrell, Steve Carrell, Paul Rudd and David Koechner were set to appear - sure didn't they record their segment when they were in town earlier this week, and in full Irish attire too? - but we had no idea that Ron Burgundy would be meeting Bryan Dobson. Talk about your anchormen, eh?

Ryan will also be joined by Donegal's favourite son, wee Daniel O'Donnell, who we're sure will offer up a tune and a bit of chat. Whether you think he's marvellous or find his fame utterly mind-boggling, you've got to admit the man's done well for himself. Chances are we'll also get to hear how wife Majella is getting on: Sure how could we forget the time she shaved her head on the show to raise money for cancer research?

However, we think the real highlight has to be Commander Hadfield. Yup, that's right, the amazing astronaut who brought space back to us here on earth, is due to make an appearance to coincide with his book signing in Easons over the weekend.

Now, if that doesn't nab a few viewers from Graham, we don't know what will. Speaking of Mr Norton, he's got Idris Elba and Julie Walters on the couch this eve.
