Ah, "The Sash". Isn't that the tune Tommy Makem used for his song about the bombing of Nelson's pillar back in 1966. And a grand laugh was had by all. Seems like Aine has sung a song called "Belfast Champ and Fry" (or something close to that), also to the "Sash". Politics aside, folkies of all stripes rarely have any hesitation about "borrowing" a good, singable melody.
