The Singer Takes It All (Channel 4, 9pm)

AND now, the end is here, and so I face the final curtain… or in this case a conveyor belt while singing and the public voting by mobile phone app to let you continue or depart through the flaps. It sounds like a bit of a filch from chat show Graham Norton’s comedy chair of doom.

Presenter Alan Carr admits he had his reservations and says: "When they said it was a singing show, I thought 'No, no, no!' But when I saw this app, I thought it felt really different. While the singers are performing their song on the show, they're standing on a conveyor belt called The Track. If you like them, you press Hit, if you don't you press 'miss'. The more hits they get, they move towards the gold zone, where they could win up to £10,000. Or, if it's all Misses, you could disappear backwards through the flaps to a life of misery."

He adds: "But people can't vote unless they've downloaded the app. Well, they can shout at the telly, but it's not going to make a blind bit of difference."

The Chatty Man star has a dig at other talent shows by adding that this isn’t about getting record sales of ten million, but more like karaoke down the pub. "And there's all of that rubbish on the talent shows of 'I don't like you… I LOVE you!', 'You're a dark horse’, 'This competition just got exciting.' Here there isn't any of that, it's stripped bare. Nobody's cat has just died," Carr says.

What The Singer Takes It All does have though is a celebrity guest who will give a bit of guidance and feedback – and Carr has some practical advice of his own for the would-be warblers. "I've been on the conveyor belt, and it's very off-putting. When it jolts when you hit a bum note and the audience decides that you're rubbish, and it starts to move, it's really tricky.”

However, he admits he's in less of a position to give pointers on vocal technique. "I can either do really low, like Barry White, or high like the Bee Gees or Kate Bush. There's no happy medium with my voice, I'm afraid. Actually, I wanted to sing a song at the end of the show like Cilla Black did on Surprise, Surprise. Strangely, they said no."

The Commonwealth Games (BBC1, 7pm)

WITH the final of the men's 10,000m minus Mo Farah, this evening’s highlight may well be a fleeting glimpse of Usain Bolt in the 4x100 relay. Kenyan Ezekiel Kemboi is another Olympic gold medallist expected to reach the final of the men's 3,000m steeplechase. There’s also the finals of the men's pole vault and women's 800m, 100m hurdles, high jump and discus, plus the heats of the men's 1500m, and 4x400m relay.

Elvis: That's All Right 60 Years On (BBC4, 9.10pm)

NOTING the sixth decade since Elvis's foot-tapper That's All Right was recorded at Sun Studios in Memphis, Tennessee, sees actor and musician Sam Palladio tracing Elvis from an impoverished childhood to the moment he entered a recording booth to perform the track. Penned by Arthur 'Big Boy' Cruddup, and recorded by him in 1946, it was of course Elvis' version, recorded on July 5, 1954, that made it immortal. Candi Staton, the Pierces and Laura Bell Bundy will be performing some of Elvis' best-loved tracks.
