Jimmy Carter: Rock & Roll President (Sky Arts, 9pm)

IF it hadn’t been for a bottle of Scotch and a late-night visit from musician Gregg Allman, Jimmy Carter might never have been elected the 39th president of the US.

This engaging documentary charts the mostly forgotten story of how Carter, a lover of all types of music, forged a tight bond with musicians Willie Nelson, The Allman Brothers, Bob Dylan and others. Low on campaign funds and lacking in name recognition, Carter relied on support from these artists to give him a crucial boost in the Democratic primaries.

Once Carter was elected, the musicians became frequent guests in the White House, and played a significant role in Carter’s life.

Celebrity Catchpoint (BBC1, 6:30pm)

PADDY McGuinness is back to host four celebrity editions of the family-friendly game show combining physical fun and tricky multiple-choice questions. Each question Paddy asks has 10 sequential answers, each corresponding to a position on the straight line of circles on the floor. The contestants then pick a spot to stand on and if it’s right, they’ll have a better chance of catching the prize ball that drops from the ceiling.

It’s a fun game but, given they are fundraising for charity, there is a lot at stake for the celebs taking part. Tonight, Radio 1 DJs Matt Edmondson and Mollie King are up against presenter, author and columnist Dr Ranj Singh and Olympic long jump gold-medalist Greg Rutherford.

The Masked Singer (STV, 7pm)

IN the first two weeks of this year’s competition, we saw ubiquitous Murder on the Dancefloor hitmaker Sophie Ellis-Bextor unveiled as the Alien, while Spice Girls icon Mel B was forced to whip off her seahorse mask.

So which celebrity in their ever flamboyantly elaborate character costume will join the duo and be voted out tonight? Host Joel Dommett presides over the fourth edition of the unique entertainment guessing game, with celebrity sleuths Mo Gilligan, Davina McCall, Rita Ora and Jonathan Ross looking for clues to who are behind the masks.

The Voice UK (STV, 8:30pm)

THE blind auditions continue in the third instalment of the spinning-chair singing contest, as will.i.am, Sir Tom Jones, Olly Murs and new coach Anne-Marie search for a singing superstar.

During this stage, the four coaches will each have the opportunity to stop a fellow coach from adding a singer to his or her team, but they will get only one chance to use their Block and weaken the chances of the other coaches. As usual, Emma Willis is on hand to congratulate the chosen singers, as well as commiserate with those who don’t make it.
