Tonight's TV highlights

Turn Back Time – The High Street 9pm, BBC1 The shopkeepers and their families make another temporal shift, this time to the 1930s. The children of Shepton Mallet practically kick down the door of Sergison's grocers when they see the mountain of sweets on offer. "I wish I could be in olden days," gushes one cherub. Baker Caroline is sent for cookery lessons to cure her of her cake phobia. Was she attacked by a Battenburg when small? The butcher's son is turning into a total bread-head and sulks when his dad won't go all out for profit. Next week, it's war. JNR The Glasgow Boys 9pm, BBC4 Glasgow's contribution to the artistic heritage of these islands is an extraordinarily rich and under-regarded subtext, in terms of architecture and music especially. As this documentary by native daughter Muriel Gray reminds us, however, the city has been no slouch in the visual arts either. The Glasgow Boys were a loose association of young, late-19th-century painters who tended towards realist renditions of everyday, outdoor scenes of Scottish life – and who, at the time, created a minor international sensation. Gray considers the work of Lavery, Guthrie, Henry, Hornel and others, from their inspirations to their legacy. AM The Family 9pm, Channel 4 A welcome return for a third series of the reality show that can perhaps lay closest claim to being "fly-on-the-wall". Wall-mounted cameras catch the Adesina family in east London as they get on with running their restaurant and preparing for the 60th birthday celebrations of pa Sunday. Contains the usual family arguments and tears, but mostly the real family love that's hard to replicate even in the best fiction. WD True Stories: Tyson 10pm, More4 James Toback's 2008 film is told entirely by the ex-champ himself, occasionally using multiple frames and overlapping voices to signify his swings from nihilistic rage to a thoughtful, humble, confessional sort. However, frank as Tyson is – revealing a frightened human being beneath his terrifyingly masculine exterior – his account cries out for challenges, especially when it comes to his version of the rape for which he was convicted. The film is leavened with fight footage, most impressive in the late 1980s. DS Lip Service 10.30pm, BBC3 It's the last episode in the series, and everything has imploded, now that the entire gang have discovered that Frankie and Jay's destructive tendencies are not very easy to tame. There's further drama for Frankie when she discovers the truth about her family, and choices to make for Cat, who is finding herself increasingly torn between her old best friend and her reliable new cop. Suitably, it's an episode with a very morning-after feel, with enough half-finished storylines to keep it open for a second series. RN Imagine 10.35pm, BBC1 Alan Yentob's arts magazine returns with a profile of Ai Weiwei , the Chinese artist who recently delighted and perplexed London with his installation of a hundred million ceramic sunflower seeds, scattered on the floor of the Tate Modern. The film has been overtaken slightly by events – Weiwei was placed under house arrest in Beijing earlier this month – but this was always a risk with a subject so outspoken. Weiwei has also made something of an art form of his activism against China's dictatorship, perhaps understanding that a high international profile is his best guarantee of safety. An extraordinary artist, and an extraordinary character. AM
