My dad has just rung me up. HE'S IN THIS SERIES OF DOCTOR WHO.
He's doing the voice of a CGI creation - big one, though, in two episodes, ROCK AND ROLL MY GOD - so they've only just asked him, 'cause they didn't need to record it until now. MY DAD'S GOING TO BE IN DOCTOR WHO. UM, AGAIN.
Just thought I'd let you know.
