And Spaw, knowing you, I thought it was probably a joke (and yes, I know the "Who's on first?" routine), but in case it wasn't, and in case there were others reading who didn't know, I used it as an opening.

David Tennant was fine. But I couldn't stomach Russel T. Davies' direction for the show, and much prefer Moffatt's writing.

Back in November of last year, Matt Smith was a guest on The Late, Late Show with Craig Ferguson, to promote the US release of the latest season on DVD. And in the cold open, Craig did a song and dance number to the Doctor Who theme, explaining the premise of the show to his American audience. You can see it here:
