We're Going to Hang out the Washing on the Siegfried Line

"We're Going to Hang out the Washing on the Siegfried Line" is a popular song by Ulster songwriter Jimmy Kennedy, written whilst he was a Captain in the British Expeditionary Force during the early stages of the Second World War, with music by Michael Carr. The Siegfried Line was a chain of fortifications along Germany's Western border, analogous to the Maginot Line in France. The song was used as a morale-booster during the war, particularly up to and during the Battle of France.

It began:

Leslie Sarony (1897–1985) and Leslie Holmes added some possibly unofficial lines. The Sarony and Holmes version put "Mother dear, I'm writing you from somewhere in France" at the start and then, after the main section, added four lines starting "Everybody's mucking in and doing their job".

At the first big wartime variety concert organized by ENSA, which was broadcast by the BBC from RAF Hendon in North London on 17 October 1939, Adelaide Hall performs the song accompanied by Mantovani and his orchestra. A rare Newsreel of this concert showing Adelaide Hall singing We're Going to Hang out the Washing on the Siegfried Line accompanied by Mantovani and his orchestra still exists, and the footage is thought to be the earliest surviving film of a performer singing the song.
