It was the version of The Nightingale,or The Bold Grenadier that begins "One morning, one morning, one morning in May, I spied a young couple a-making their way"; IIRC Bonnie Sartin recorded it with the Yetties: different tune and text from the "Kissed so sweet & comforting" variant. I once mentioned this in the course of a Guardian correspondence on the song as the source of the tune of The Patriot Game, and Dominic replied by admitting it had been the source of the air he had used; I still have this correspondence on file somewhere, I think: so Dominic seems to have {if may so put it} changed his tune over the years.

Ah, yes, Jo Stafford. It was Allentown Jail that I always particularly loved her singing.
