This thread has been an amazing journey. Now I finally get to hear it from the source!
   It's interesting that Women, Women and Song, along with Tom Rawson, sing it as musicians who keep up a regular pace. Because, as noted several times, I only play autoharp and can only get about 3 of those keys/chords, I ham up it up with pauses and contortions looking for vaguely useful chords.
   When I first learned it, I had no idea how to record it or post it online. Now, I ought to make an attempt to let everyone hear how I sing butcher it. I do know now how to post to YouTube, so I will make an attempt 'soon'... (lots to do the next couple of weeks)... then I will pretend to tune the autoharp and have at it.
Watch this space.
