Sorcha,

No, it's a case of someone singing 'The Black Velvet Band' to me last night, and my mind suddenly associating with something else.

As I said Maddy Prior came to mind, but who knows...

It may possibly be the case that it's just a song with a very similar melody, I'm not sure.

But it's bugging me like hell, I've racked my brains more than brains should healthily be racked...
