Bob, if you go up to the top of this thread and click on the MIDI link, your computer will (probably) play the tune that Philippa transcribed.
It's a little different than the tune I learned from Susan Frank, who learned it from Sandy and Caroline, who learned it from David Hammond's recording, as it says above.

Blessings,
Barbara,
and is there a way to get a copy in any form of Son of Child?
