Interesting seeing this thread come up again. I met Peter, when I had to pick him up at the airport in Chicago way back in the late 1980's. I loved his singing and performance style. I had to convince him it was really impractical to drive over to Joliet prison (which was featured in the film The Bluesbrothers) I did promise to drive him under some el tracks,which also appeared in the film. However the reason I'm posting this is that my wife and I have retired from our days jobs and are still doing music. We supplement our pension income by substitute teaching. I was subbing for an english lit class in Sault Ste. Marie, Michigan and heard some sophomore girls quietly singing the chorus of Oak and Ask and Thorn. I finally asked if that's what I was really hearing. They said they were singing it in choir and really liked the melody. They were surprised when I told them I'd met the man who composed that tune. The choir was not singing all the verses, unfortunately (some religious folks would probably object to the "do not tell the priest this night" verse). I suspect Peter would have been suprised that some choir teacher in the far reaches of the Northern US would be having kids sing his melody.
