Ruthie,I've got it on a video of the Cambridge Festival from a few years back. Unfortunately my VCR isn't working at the moment, but if you get no luck, I'll transcribe it as soon as I can.
What you remember of the lyrics and the chorus is right, unfortunately I can't remember much more myself.
I have heard that you can get lyric request by emailing Kate's website www.purerecords.demon.co.uk, so if you can't wait for my video to be fixed you could try there
