"Jamie Foyers" is a song by the folk singer and songwriter Ewan MacColl.
In The Essential Ewan MacColl Songbook, Peggy Seeger wrote that the song was written in the period 1937-1939 but could not give an exact year (although it is difficult to see how it could have been written before the First Battle of Gandesa in April 1938).
[1] It tells the story of a shipyard worker from the Clyde who goes to fight with the International Brigades in the Spanish Civil War.
MacColl adapted it from a traditional Scottish song about a soldier who fought in the Peninsular War, only retaining the first verse.
There is a last verse in some recordings of the song that does not appear in the version in The Essential Ewan MacColl Songbook.
