Can't add much to the above.

I know Bonny Kells Water was sung by Andy Irvine with Planxty in the '80s. Not sure if it was recorded (maybe on Words and Music?). If your version is 40 years old it predates this anyway.

I first heard Mary rather than Frances Black singing Loving Hannah, I've a notion her source was Frank Harte, but amn't certain of that. It may well have been in the family repertoire.

Ye Jacobites by name shares a tune with the Irish Famine song "The Praties they go Small"

Is "The Lark in the Morning" a song or a tune?
