Q - don't know if the Ballet ms was ever published. Many of the lute mss are available (courtesy of enthusiastic scholars and players) in transcriptions for the tablature programs Django and Fronimo (used for various early tablatures beside the lute). Ballet doesn't appear to be amongst them.

John Attey appears to have set the song in his First Book of Ayres (1622) and I have the tablature for that. Sadly it's a pdf of the lute tablature, not source for the programs, so I'll need a while to transcribe some of it to see if it bears any relation to the other versions. I'm off to bed now, so that'll have to wait until tomorrow. I'll report back then!
