What's on TV: eight shows to watch this week

The Mario Rosenstock Show
Sunday, RTÉ One, 9.30pm
Joan Burton, Miriam O'Callaghan, Vincent Browne, Donald Trump and . . . hang on – is that the real Louis Walsh? Ireland's favourite impressionist is back in The Mario Rosenstock Show, and this time he's got something a little different up his sleeve. The new series is filmed in front of a live studio audience, and as well as doing his best-known celebrity take-offs, Rosenstock is inviting real guests to join in with the general urinary extraction. So the real Louis Walsh, Keith Duffy and a variety of musical guests are starring alongside Rosenstock's cast of larger-than-life characters. "It's not going to be sketch, sketch, sketch – it's kinda a Sunday night entertainment show," says Rosenstock. As long as it makes us laugh, Mario.

Footballers, Sex, Money: What's Gone Wrong?
Tuesday, BBC Three, 10pm
Young, talented, rich and famous – the life of a premiership footballer is one to be envied. But are the players getting out of hand, and is it all going to their heads? In Footballers, Sex, Money: What's Gone Wrong? , Amal Fashanu looks at the promiscuous lifestyles that go with being a young football star earning five-figure sums in a week, and asks if the game is fostering dangerous attitudes towards women. She also meets the footballers' wives and girlfriends, to find out how they deal with the constant pressure of keeping their men from going offside.

Party Pills: Reality Bites
Thursday, RTÉ Two, 10pm
I know what you did last weekend. Ireland's recreational drug culture is alive and well, and still partying on into the small hours of the morning. Party Pills: Reality Bites explores the world of class A drug use in Ireland, from ecstasy to benzodiazepines, among well-off young people looking to fuel their 24-hour party lifestyles. It's billed as a non-judgmental exploration of Ireland's pill-popping culture that listens to the views of drug users, recovering addicts, paramedics and parents whose children never came home from the party. The documentary also looks at drug-dealing on the "darknet" and hears how Minister for National Drugs Strategy Aodhán Ó Ríordáin is tackling the problem.

Adele at the BBC
Friday, BBC One, 8.30pm
The biggest musical event of 2015 is not 1D or U2, but the arrival of album number three from Adele Adkins. The world has been waiting four years for the follow-up to her all-conquering 2011 album, 21, and the wait finally ends on Friday with the release of 25. To celebrate, a one-off special, Adele at the BBC will see the singer perform some of her now-classic hits, as well as tracks from her new album, and chat to host Graham Norton about her life and music. "The BBC has been wonderful to me over the years, and Graham and I get on great, so it's going to be a laugh," says Adele. Expect viewer figures to go through the roof – if they haven't already been lifted by Adele's fantastic voice.

Kitchen Hero: Cook, Eat, Burn
Friday, RTÉ One, 7.30pm
He's the youngest celebrity chef on the block, but already Donal Skehan is looking like a veteran of the vittles. He's just published his fifth cookbook, Fresh, and it's been shortlisted for the Bord Gáis Energy Irish Book Awards. His latest series, is not about about burning the dinner – it's about knocking up healthy meals to provide us with the fuel we need to power our active lives. Each week, Skehan embarks on a fitness challenge, cooking up recipes designed to help him through the gruelling test ahead. In episode one, Skehan devises a slow-burn recipe to sustain him on a climb up Carrauntoohil. "Last year I reached a point of just absolute exhaustion, I had a hectic schedule, and I thought, this is crazy." And now? "I can't tell you how much energy I have, and I can only attribute it to the food I eat."

Mercury Prize Live 2015
Friday, BBC Four, 9.30pm
Who has released the best album of the past year? Was it Florence + the Machine or Róisín Murphy? Gaz Coombes or Aphex Twin? SOAK or ESKA? Mercury Prize Live 2015 is presented by Lauren Laverne and runs down the list of 12 artists nominated for the prestigious music award, considered by some as a poisoned chalice, but acknowledged by many as a platform for bringing quality music to a wider audience. It didn't do much for the likes of Roni Size or Speech Debelle, but then it didn't do Elbow or Arctic Monkeys any harm. Whatever fate awaits this year's winner, an evening of eclectic and interesting music is guaranteed.

The TV3 Toy Show
Friday, TV3, 8pm
The Late Late Toy Show has ruled the playground for years, but The TV3 Toy Show is looking to tear Ryan Tubridy's playhouse down with a 90-minute festive spectacular featuring a swarm of young singers, dancers and toy testers. Presenters Brian Ormond and former Rose of Tralee Maria Walsh mount a two-pronged attack on Tubs, helped by some special guests and an arsenal of this season's most popular toys. "I've always wanted to host a toy show. I'm a bit of a big kid myself," says Ormond. Who's the toymaster supreme – Ryan or Brian? Gentlemen, choose your light-sabre.
