The working title for this was "The Man Who Made Dad's Army": what a wonderful epitaph that is. A glorious mix of characters and elements, Dad's Army will live for ever. The show's co-creator, David Croft, made us love and laugh at the Home Guard's superannuated soldiers. Rheumatic, croup-stricken, effete or miserly, each one was a hero.

That show alone guarantees him comedy immortality, but producer/writer Croft had many hitcoms, from concert-party campery in It Ain't Half Hot Mum to shop-floor shenanigans in Are You Being Served? This tribute to Croft, who died in September, salutes a bona fide comedy connoisseur.

David Croft, who died in September, will go down as one of the most influential behind-the-scenes figures in the history of British TV comedy, having co-written and produced a raft of our most popular sitcoms, including Dad's Army, 'Allo! 'Allo! and Are You Being Served? This hour-long documentary celebrates his work, alongside that of long-term collaborators Jimmy Perry and Jeremy Lloyd - and features more than a few riotously funny clips from the shows themselves.
