Who Do You Think You Are Kidding, Mr. Hitler? (Full Dad's Army Theme) - Bud Flanagan

Dad's Army's theme tune, "Who do you think you are kidding, Mr Hitler?" was Jimmy Perry's idea, intended as a gentle pastiche of wartime songs. It was the only pastiche in the series, as the other music used was contemporary to the 1940s. Perry wrote the lyrics himself and composed the music with Derek Taverner. Perry persuaded one of his childhood idols, wartime entertainer Bud Flanagan (1896-1968), to sing the theme for 100 guineas (equivalent to £1,900 in 2019). Flanagan died less than a year after the recording. At the time it was widely believed to be a wartime song.

The version played over the opening credits differs slightly from the full version recorded by Flanagan; an edit removes, for timing reasons, two lines of lyric with the "middle eight" tune: "So watch out Mr Hitler, you have met your match in us/If you think you can crush us, we're afraid you've missed the bus." Bud Flanagan's full version appears as an Easter egg on the first series DVD release and on the authorised soundtrack CD issued by CD41. Arthur Lowe also recorded a full version of the theme.

The music over the opening credits was recorded at Riverside Studios, Bud Flanagan being accompanied by the Orchestra of the Band of the Coldstream Guards.
