Isn't that a William Walton piece from his Henry V music rather than a folk tune? (sorry...just being pedantic!)

I don't know that record, but Erskine also recorded it on one of the trio albums he made with John Taylor on ECM. It's a lovely tune.
Yes, it was written for Henry V. But I've always believed the melody is based on a folk tune, or maybe it's the way Lovano plays it. It's become something of a jazz standard since Erskine's version. Lord lists some 15 or 16 recordings. Apart the versions quoted above, another posiible notable recording was made by Lynne Arriale. I can recall reading a cd review not so lomg ago whiche credited the pice to Cedar Walton!
Sweet Soul is a fine album which I can recommend.
