WHAT can't you miss on TV tonight? Our guide to the must-see shows...
A Night for the Emergency Services, 9pm, ITV
Ashley Banjo hosts this glitzy event where some of our frontline heroes get to show off their entertainment skills.
The Cheshire Fire Choir hit the stage with Leona Lewis (right); PC Paul Taylor – who became a viral star when he was pictured dancing with kids at the Manchester One Love concert – dances with Diversity; and Mark Daniels, an RNLI volunteer, performs a Michael Bublé tribute.
There’s an impressive finale featuring Britain’s Got Talent winner Tokio Myers, too.
A wonderful celebration for the heroic men and women who are always there when we need them.
Peaky Blinders, 9pm, BBC Two
The stage is set as this fourth series comes to an end with Tommy (Cillian Murphy, right)and Luca Changretta heading for another face-off.
There’s also Arthur in the midst of a drugs binge and the prospect of an arms deal with the British military.
Get set for series five.
The Real Marigold on Tour, 9pm, BBC One
It may be cold, but that doesn’t mean there isn’t plenty to enjoy in Iceland for Sheila Ferguson, Dennis Taylor, Paul Nicholas and Rustie Lee (l-r).
Visiting a small fishing village and the capital, Reykjavik, the foursome experience whale-watching, Sheila goes on a date and Paul attempts a handstand.
Who said pensioners don’t have a wild side?
The Secret Life at Christmas, 8pm, Channel 4
If you’re thinking of what gifts to buy for everyone in your family, spare a thought for Chester Zoo’s keepers – including Holly (below) – who have to make presents for the animals.
And when parcels are delivered to the chimps, their leader Dylan is otherwise occupied, so squabbling breaks out among the group. They may be even more human than we’d thought.
Judi Dench: My Passion For Trees, 8pm BBC One
As well as being an Oscar winner and a national treasure, Dame Judi (above) is also a closet tree-hugger.
This one-off special sees her inviting us into her own private forest at her home in Surrey and marvelling at the wonders of nature.
Just call her the new Attenborough.
