The Jonathan Ross Show, 9.55pm, Comedy actor David Walliams talks about his River Thames swim that raised more than £1million for Sport Relief, and his plans to write a children's novel. The host also welcomes actor Seth Rogen, who discusses his role in the comedy film 50/50, and singer Michael Buble, whose latest album Christmas is released this month. Plus, Coldplay perform their single Paradise from their not at all pretentiously titled new album Mylo Xyloto. If that is in fact the name of somebody dear to them, I do apologise.
