In another thread I mentioned that there are a great many Turkish songs from WW1, both about Gallipoli and about the Mesopotamian campaign. There is an album of them by Ruhi Su, "Seferberlik Turkuleri" (Songs of Mobilization). And "Burasi Mustur", which I don't think Su recorded, became something of an anthem, covered by many singers, after the US started blasting the hell out of Iraq, because of its historical parallels.

But I can't think of any song from the British side in Mesopotamia. Are there any? You'd think there'd be a song about the Siege of Kut, at least.
