MacColl made 2 LPs of Burns songs; 'Songs of Robert Burns' on Folkways (more recently released on Ossian) and 'The Merry Muses of Caledonia', a (very) limited issue on the Dionysus label (does anybody know of any other releases on this label? - I suspect it was a one-off).
IMO the 'Caladonia' album showed both Burns and MacColl at their best.
Bob Blair makes an excellent job of Burns (composed and collected) songs
