Miriam Margolyes joins the cast as Colin's forthright grandmother, while Colin himself (Carl Rice) goes power crazy when he is promoted to management. Gareth's All-Star Choir Gareth Malone forms a choir of celebrities (including Alison Steadman, Craig Revel Horwood, Jo Brand and Mel Giedroyc), with the aim of recording this year's Children in Need single. Intruders There's a lot of driving at night in the rain in this week's episode of BBC America's body-snatcher drama, as John Simm's ex-cop continues looking for his wife (Mira Sorvino). Micky Flanagan's Detour de France 9pm, Sky1 "It's not a travelogue," insists Flanagan. We're going on a jolly-up.

Toast Of Britain 10.35pm, Channel 4 Steven Toast is recording "mind the gap" announcements for Transport for London when we rejoin Matt Berry's bombastic actor for a fresh run of this politically incorrect romp.
