There's a poem which has been set to music called "Capernaum".
"If all the blood spilled at thy Tron, Edinb'ro, Edin'bro
If all the blood spilled at thy Tron had fell intae the river
Twould ca' the mills o' Bonnington, Edin'bro, Edin'bro
Twould ca' the mills o' Bonnington, for ever and for ever"

There's more but I can't remember it.
