After I posted that last message I did a search on Allmusic.com & found that Paul Hillier recorded it with "Theatre of Voices" and it has been released on at least 3 recordings. You have to login to Allmusic, so I'm not going to try to create a link. A song search of Apple Tree will turn them up. There a sound clips of slightly different sections. One starts with the 2nd half. They've also rearranged the words so the 2nd half is another verse, instead of a chorus.
