Comedienne and “Doctor Who” sidekick Catherine Tate and “Jekyll” star James Nesbitt both joined Graham this episode. Hmmm…Tate and Nesbitt? Was it possible that we were looking at the new “Doctor Who” team? Nesbitt said he knew nothing about replacing David Tennant as Time Lord. “I wouldn’t put a lot of money on it…I would find it very hard to follow David Tennant [but] my daughters would worship me forever because they’re obsessed by it.”

Catherine Tate, who had been embraced by skeptical fans on “Doctor Who,” said she’s not returning to “The Catherine Tate Show” for a while, but she “wouldn’t rule it out – specials or something with the old lady character.”

Indie band The Kooks performed live in the studio.
