Have looked at the ABC and done a conversion to notation: the notes look about right compared to how I have heard it sung, but the note lengths and therefore timing is not as I know it. Will have a crack at scoring it myself, but I think it's mainly in 3/4, not 4/4 as the first 2 notes of many bars are quavers and not crotchets! (Tho' not waltzy as there are also some longer held notes!)
