Between 1968 and 1977, the BBC broadcast 84 television episodes of 'Dad's Army'. Across nine seasons and seven Christmas specials, the programme continues to be one of the most beloved of all British sitcoms. However, not every episode of 'Dad's Army' still survives in its original format. Five episodes were never formally archived by the BBC and are today presumed lost. No footage is known to exist from any of these episodes. They are collectively some of the most sought-after of all lost television programmes.

Happily, audio-only recordings have survived of all five of these lost classics. These audio recordings (starring Arthur Lowe, John Le Mesurier and Clive Dunn) have been painstakingly reassembled and restored and are now used as the basis for a series of new animated episodes of 'Dad's Army' - featuring all new hand-drawn black and white animation, synced up to the words of the original actors.
