G'day,
Thanks to Ivan the tune for "All In A Garden Green" can be found here at the Mudcat MIDI site.
Ivan says: This was prepared by transcribing from a .wav of Dave Oesterreich's singing the first verse. I've also sent Joe Offer the NoteWorthy file for it. Don't know much about it, but I found the tune in an abc of the 1651 Playford Book, so I guess it's pretty well traditional.
Cheers,
Alan
