Dolly: Live in London O2 Arena (BBC Two, 4.20pm)

What's it all about? The 2008 concerts by the Queen of Country, Dolly Parton, at the O2 arena were hugely popular, and the BBC has pulled off a major coup in showing the footage that has sold so well on DVD.

In it, she wows a sellout crowd with her inimitable voice and country charm. Not only that, but she plays up to her image in fine style. Remember, this is a woman who describes her image as a cross between "mother goose, Cinderella, and the local hooker."

Look out for: During the sensational set, Dolly performs many of her classic hits such as "Two Doors Down," "Jolene," "Coat of Many Colors," "Here You Come Again," "9-5," and I Will Always Love You" as well as new songs from her most recent release, Backwoods Barbie.

If you only know Dolly for the cartoon character image she projects, prepare to be amazed by the musical abilities of a true country colossus.

Mrs Mandela (BBC Two, 10.50pm)

What's it all about? Nelson Mandela is a man who needs no introduction. But what about Winnie, the woman who waited for him while he languished in a South African jail for 27 years? Much has been written about her controversial activities, including allegations of kidnapping and a conviction for fraud. Nevertheless, the woman herself remains something of a mystery. With a bit of luck, this feature-length drama, which was first aired last week on BBC Four but makes its terrestrial TV debut here, should give us an insight into what makes an extraordinary - if flawed - individual tick.

Look out for: The top-class cast, which includes Sophie Okonedo and David Harewood as Winnie and Nelson Mandela, and David Morrissey as a notorious police interrogator. But their performances would be nothing if it wasn't for the excellent script by Michael Samuels. Expect awards a-plenty for what promises to be one of the outstanding dramas of the year.

The Gadget Show (Five, 8pm)

What's it all about? In the first edition of a new series, Suzi and Jason face their most punishing challenge to date when they're dumped in the Liwa desert in Abu Dhabi - which is considered to be one of the most arid and inhospitable places on Earth.

Thankfully, the intrepid duo have a range of gadgets on hand to help them survive the extreme environment. The pair then conclude their challenge with a sand race, with both driving the latest in desert vehicles. Meanwhile, Jon travels to the Caribbean to test the latest generation of e-readers, and Ortis examines what will be this year's must-have gadget.

Look out for: Ortis Deley's predictions for which products will be the most sought-after this year as this segment gives viewers the chance to see what will be hot in 2010.

Survivors (BBC One, 9pm)

What's it all about? Since the post-apocalyptic drama, following a small group of people who survived a flu pandemic that wiped out most of the human race, returned it's been better than ever, but it's still doing just as good a job at reminding us that the world in the very near future could be a dismal place indeed.

Look out for: Max Beesley, who plays murderer Tom Pryce, as he lands in some hot water in this latest episode.

Last surviving member of the government, Samantha, orders henchman Dexter to arrest Tom as she hopes to reintroduce the judicial system, and plans to put Tom on trial for the murder he previously committed against one of her people.

Abby has little choice but to lead Anya and Greg in pursuit, later taking on the role of counsel for the defence, while her colleagues become members of the jury.

However, when Tom's brutal past is finally revealed, the group is stunned by his secrets.
