Traditional Breton song
"An Alarc'h" ("The Swan") is a Breton traditional song. It is found in the 1839 collection Barzaz Breiz. It tells of the return from exile in England of the Breton prince Jean de Montfort (known as "The Swan of Montfort") and his defeat of the French army under Bertrand du Guesclin in 1379. It has been recorded by, amongst others, Alan Stivell and Gilles Servat.
The Scottish folk song "The Twa Corbies", a variation of the English song "The Three Ravens", was set to the tune of "An Alarc'h" by R. M. Blythman.
