Three decades after it first appeared on screen, Father Ted is still cherished, quoted and endlessly re-watched. Its beloved main characters, unforgettable lines and extraordinary visual jokes have given birth to a thousand gifs and t-shirts and a million catchphrases.

Unforgettable to watch, it was also unforgettable to work on. Lissa Evans, as producer of the second and third series, spent three years hovering anxiously over every moment, from the first glimpse of script to the last revolution of a runaway milk-float round a specially-built plywood roundabout. There was no 'average Father Ted episode' - each of them was stuffed with challenges; endless rain, lustful rabbits, clerics crashing through windows, sheep doubles, collapsing crosses and a never-ending stream of eccentric priests - and the work that went into its creation was often nearly as bizarre as what was happening on screen.

Picnic on Craggy Island is a hugely affectionate and anecdotal account of what lay behind some of those moments of comic genius - so pull on your kagoule, spread out your blanket, unwrap the sandwiches (they're all egg) and enjoy the picnic?
