Tonight's top telly includes Tommy Tiernan (of course!), Dave Allen, Ant & Dec, Carly Simon, Poly Styrene and some cracking movies . . .

Pick of the Day

Ant & Dec's Saturday Night Takeaway, 7.00pm, Virgin Media One

It’s not the same as it used to be - sure, what is? - but this show is still a fun lift of a Saturday evening.

Comedian and actor Rob Delaney is this week's guest announcer, TV presenter Davina McCall (below) is the latest victim of Get Out of Me Ear, and singer Tom Jones is in the studio for an End of the Show Show with a difference.

Plus, Stephen Mulhern is back for an Ant v Dec challenge and another lucky viewer gets the chance to Win the Ads.

Don't Miss

The Tommy Tiernan Show, 9.25pm, RTÉ One

As usual, we have no idea who’s going to be talking to Tommy on this week’s show. Neither does he, which makes all the difference.

Last week, for example, he was joined by comics and podcasters The 2 Johnnies. It was fun.

Tonight it could be deadly serious. But it will always be entertaining.
