Cher at the BBC (BBC2, 9.00pm)

THESE “... At the BBC” specials, usually found over on BBC4 and often tucked away quite late on in the schedules, are veritable treasure troves of rare performances of hit songs.

This one sees the singer, Oscar-winning actor and “Queen of Re-invention” Cher in her various guises and modes as it scours the Beeb’s archives going back decades for some of her best shows.

Everything from big concerts and arena shows to more intimate, studio-based sets are featured, and with a career dating back to the 1960s (Cher, unbelievably, has just turned 75) there is a wealth of hits for the programme’s makers to choose from – encompassing genres from rock and folk to disco, electronica, dance and, of course, pop.

The Masked Dancer (ITV, 7.00pm)

ENTERTAINMENT shows rarely arrive out of nowhere – often their origins can be traced back across several formats from various networks or even countries.

This is the perfect example, being a reworking of ITV’s recent popular series The Masked Singer, itself an import from the US, which actually took the idea from a show in South Korea.

The title explains much – essentially our incognito performers will be showing off their moves rather than their vocal chords, and we can be sure that there will be a good mix of celebs from the capable to the less convincing (expect the dad-dancers to be whittled out in the early episodes). The series is on all week, so no waiting until next Saturday for your next fix.

The Wall (BBC1, 8.05pm)

ACTOR, soap star, distant royal and game show host Danny Dyer already has a pretty varied career, and now he might be able to add wedding planner to his CV as he welcomes an engaged couple from Hamilton in South Lanarkshire, just south of Glasgow, to his big-prize game show.

They’re eager to start their married life together in style, and a life-changing sum of money courtesy of Dyer’s prize fund would certainly help. First though they must prove they’ve got what it takes to take on the Wall.

Beat the Chasers – Celebrity Special (ITV, 8.30pm)

CELEB quizzers are all the rage on ITV today, with a repeat of The Chase Celebrity Special and a brand new Catchphrase Celebrity Special, before this one, which sees five famous faces take on the quintet of quiz kids.

Gregg Wallace, Brenda Edwards, Jake Wood, Dom Joly and Krishnan Guru-Murthy make up the contestants, all hoping to build up a decent jackpot to take back to their chosen charity – while Mark Labbett, Anne Hegerty, Shaun Wallace, Jenny Ryan and Darragh Ennis are, rather uncharitably, trying their best to stop them.

Blinded: Those Who Kill (BBC Four, 9pm & 9.45pm)

THE Danish drama reaches a conclusion. Unaware of who he really is, Louise gets far too close to Peter Vinge. Karina tries to find new evidence for the investigation on her own, and an earlier clue resurfaces, moving the case forward.

Peter sorts his life out and gives Johannes a message that his son has a hard time coming to terms with. Then, as the police take Johannes to the station, Peter meets his former wife Masja, who has returned from Singapore without notice in order to set things straight.

Finally, Karina, Soren and Torben desperately try to find Peter before he can claim another victim.
