I heard a version of this song in Belize with slightly different lyrics, namely: "she'll be comin' 'round the mountain when she [unknown word].' I know in the Caribbean the word 'reach' would often be used in this case (i.e. 'when did you reach?' meaning, 'when did you arrive [in town]') but I don't think this was word used in this case - I just plain don't remember to be honest. Anyone have any ideas?
