The melody has been traced back to the early 19th century. The tune of "The Sash" was well-known around Europe, and before the lyrics were added, it was a love song that lamented the division between people. Instead of "it was old and it was beautiful", the lyrics were "she was young and she was beautiful" and is in Broadside Ballads (1787),[1] titled "Irish Molly O". Another known printing of the tune is from 1876 including the words "The Hat My Father Wore".[2] The song is classified in the Roud Folk Song Index as number 4796. It has also been adapted by fans of Stockport County F.C., who call it "The Scarf My Father Wore" or simply "The Anthem".[3]
