I can't help out with the version by Jon Boden, but I'm going to send a MIDI to Joe with vocal parts, a part for a handdrum and a recorder playing along. (I wrote it just now.) I hope you can handle MIDI. If not, somebody will think of something, I'm sure.

You will have to tweak the words a little to fit the note lengths.

You will note that there is a measure which takes a C chord the first time and an Am the second. This is one of my little specialties.

I hope you like it. If you don't, you may folk process it.
