A great post, thanks mgl. Just reposted the interview on my Facebook. It's a good songwriting story! I said on FB that the devotion to the song has really stepped into the mawkish zone over the last few years, but that this reminded me that it is a very carefully crafted and memorable song. THanks.
The melody quotes a particular IRish jig that I've heard but can't put my finger on. The Chieftains' Skyline jig is pretty close.
The video reminded me that Kristy MacColl was one of my fashion icons in high school. So cute - I wanted to look just like that. I got as far as the overcoat.
