If your regular telly viewing rarely takes you beyond a few favourite channels, maybe it’s time to branch out and explore some of Freeview’s hidden treasures. There’s plenty to enjoy, from long-running dramas that have stood the test of time to classic comedies that’ll never go out of style. So, grab the remote and start discovering the great selection of hidden gems coming up this week. Whatever Happened to the Likely Lads? Yesterday (Freeview Channel 19) Friday 20 April at 9pm; 9:40pm; and 10:20pm Back in the 1970s, Bob Ferris and Terry Collier dispensed their own brand of Geordie wit and wisdom. The characters, marvellously portrayed by Rodney Bewes and James Bolam, played out the tensions between Terry’s working-class outlook and Bob’s middle-class aspirations. Tonight, when Bob throws Terry a surprise party, a blindfolded Terry begins moaning about his old pals, unaware that they’re in the same room. Taggart True Entertainment (Freeview Channel 61) Friday 20 April at 9pm As DCI Jim Taggart, Mark McManus came to embody the typical tough Glaswegian detective. In tonight’s three-part story, Taggart is extra grumpy when he has to take on an admin role. This was Mark’s last appearance in the title role, but the show retained Taggart’s name in recognition of a brand that found popularity both at home and in more than 50 countries. Midsomer Murders ITV3 (Freeview Channel 10) Saturday 21 April at 4:55pm, 7pm and 9pm A word of advice: if you ever find yourself in Midsomer, get out of there fast. With an average of 2.6 murders per episode, it’s likely you’ll either be bumped off or end up in a police cell. In this week’s episodes, members of a reading club fall under suspicion of battering a prominent villager to death, a pupil at a prestigious school dies of a stab wound while competing in a race, and two couples disappear in a wood amid rumours of witchcraft. Never a dull moment in sleepy Midsomer! Hi-de-Hi! Drama (Freeview Channel 20) Saturday 21 April at 5pm, 5:40pm and 6:20pm This is one of the great British sitcoms from the writing team of Jimmy Perry and David Croft (who also gave us Dad’s Army), recreating the chaotic fun of a seaside holiday camp in the 1950s. There are some memorable characters in this show, including the fearsome Chief Yellowcoat Gladys Pugh (played by Ruth Madoc), the scatty chalet maid Peggy Ollerenshaw (Su Pollard) and Jeffrey Fairbrother (Simon Cadell), the Cambridge professor turned entertainment manager who struggles to resist Gladys’s amorous advances. In tonight’s episodes, Peggy gets her big chance to be a Yellowcoat and Jeffrey thinks the campers deserve some culture. The Big Bang Theory E4 (Freeview Channel 28) Saturday 21 April from 5:30pm and Sunday from 1:30pm There’s a great big batch of Big Bang episodes this weekend, featuring everyone’s favourite geeks. This week, Raj’s parents set him up on a blind date, in the hope of finding him a wife, and Sheldon encounters a 15-year old physics prodigy who (incredibly) is even cleverer than him. Let’s hope he doesn’t sit in Sheldon’s spot! Line of Duty Sony Crime Channel (Freeview Channel 60) Sunday 22 April at 9pm If you’ve yet to catch up with this cracking crime thriller, now’s a good chance to tune in. Episode one of series three opens with the fatal shooting of a hardened criminal by an armed response unit. But the police anti-corruption unit gather evidence suggesting it was a deliberate killing. The acting is top notch – not surprising with Vicky McClure, Martin Compston, Will Mellor and Arsher Ali among the cast. Classic Who Wants to Be a Millionaire? Challenge (Freeview Channel 46) Sunday 22 April at 10pm and 11pm Right from its first episode in 1998, this award-winning quiz show was an instant hit. With its mixture of humour and suspense, the programme gained a massive following, and it also launched the TV career of Egghead Judith Keppel, who was the show’s first millionaire. A new series is returning to our screens next month (hosted by Jeremy Clarkson). But tonight, you can see a couple of classic episodes presented by Chris Tarrant. Auf Wiedersehen, Pet Yesterday (Freeview Channel 19) Monday 23 April at 9pm and 10pm The story of a group of Newcastle builders looking for work in West Germany seemed an unlikely concept for a TV show. But the solid writing of Dick Clement and Ian La Frenais transformed the idea into one of the best comedy-dramas of the 1980s. The show also introduced us to actors who would go on to further success on the small and the big screen, including Timothy Spall, Kevin Whatley and Jimmy Nail. Murder, She Wrote ITV3 (Freeview Channel 10) Monday-Friday at 7pm In a twelve-year run, the great Angela Lansbury made this show one of the best loved crime shows on TV, and it’s still enjoyable viewing. There’s nothing better than watching the amateur sleuth Jessica Fletcher outwit the criminals and the cops alike. This week Jessica has to put her detective skills to work in London, Hollywood and Monte Carlo. No rest for the crime-fighting novelist! Last of the Summer Wine Drama (Freeview Channel 20) Monday-Friday at 7:20pm Amazingly, the first episode of this classic sitcom first appeared in 1973. Between then and the final episode in 2010, the show ran for 31 series, and it still holds the record for the longest-running sitcom in the world. While the cast may have changed over the years, the show remained true to its roots, featuring a trio of older men and their madcap escapades in the West Yorkshire countryside. This week, Clegg (Peter Sallis) and Truly (Frank Thornton) reminisce about the accident-prone Compo (Bill Owen) and his unrequited passion for the legendary Nora Batty (the wonderful Kathy Staff). Randall and Hopkirk (Deceased) True Entertainment (Freeview Channel 61) Monday-Friday at 8pm Vic Reeves and Bob Mortimer revived this comedy drama show in 2000, but the original is well worth revisiting. After being run down and killed by a car, private eye Marty Hopkirk returns as a ghost and tries to convince his detective partner Jeff Randall that it was murder. Jeff is the only one who can see Marty, and it’s fun to see him finding plausible explanations for talking to himself. The A-Team 5-Spike (Freeview Channel 31) Monday-Friday 6pm It seems there’s no problem “Hannibal” Smith and his soldiers of fortune won’t tackle (for money). This week, they’re recruited to rescue a general and his daughter from guerrillas in Borneo, then they come to the rescue of passengers on a hijacked jet. And as if all that weren’t challenging enough, they intervene to prevent an arranged marriage between a Texan heiress and her father’s killer. Amid the action and adventure, there’s still time for comedy, and the ongoing battle of words between Murdock and B.A. Baracus: Murdock: “It’s like we’re actually being shot at!” B.A: “We are getting shot at you crazy ass fool!” Housewife, 49 ITV3 (Freeview Channel 10) Thursday 26 April at 10pm Based on a true story, this gentle drama was a departure for Victoria Wood, who was best known for her comedy sketches. Victoria plays a downtrodden wartime wife who joins the Women’s Voluntary Service and chronicles her experiences for the government’s Mass Observation project. The break from comedy paid off – the programme won two BAFTAs, including a best actress award for Victoria herself. And there are some great performances from co-stars David Threlfall and Stephanie Cole.
