First in a two-part documentary detailing the little-known story of Associated London Scripts, a workers' co-operative formed in the late 1950s by arguably Britain's most successful comedy writers of all time: Eric Sykes, Spike Milligan, Ray Galton, Alan Simpson and Johnny Speight.

[Photo caption] The scriptwriting duo of Alan Simpson and Ray Galton, creators of some of the funniest TV and radio shows ever.

Associated London Scripts 11.30am R4
This is documentary about a workers'co-operative, formed in London during the 1950s. But wait! When I tell you the show's producer is Mario Stylianides (the man who brings you Dead Ringers) and that the collective under the spotlight contains the likes of Spike Milligan, Eric Sykes, Johnny Speight, Ray Galton and Alan Simpson, you'll realise immediately that this is no worthy wade through political porridge - though it does have its fair share of angry young men. Luckily for us, any disgruntlement they felt towards society manifested itself in some of the best comedy shows of all time. This two-parter is both a biography and a celebration of the extraordinary careers and achievements of the Associated London Scripts' members. My favourite is the rise of Beryl Vertue. She describes how she was the secretary at ALS - now she runs the TV company that makes Men Behaving Badly.

Three immigrant communities reflect on the role that music plays in bridging the cultural divide between their homelands and their new lives in Britain. 2: Kiribati - Islands Here, Islands There
Palestinian singer and musicologist Reem Kelani continues her series of musical journeys around migrant communities in Britain. This week she meets the tiny community of around 30 women from Kiribati in Micronesia. Coming from a wide area in the West Central Pacific, the islanders have married Englishmen and are again dispersed, but now throughout the UK. They come together to laugh, cry, sing and dance at special occasions such as marriage and birth - and, as in this case, death. They recreate the Kiribati maneaba, or assembly house, in Fareham, Hampshire, producer Tony Phillips
