Thanks for the suggestion, Leeneia. The medley is for a Burns' night soon, so really need to stick our remit/stated goal of playing the various tunes used for the one poem, and not put in unrelated tunes, though it might do for another occasion. The American version I have was composed by Kentucky lawyer and minister, Jonathan Spilman in 1837, so pre-dates the Hume tune (1850).
I'll pm you about the Carisi tune.
