Oldtimer's version is from The Scots Musical Museum (no. 413, 1796), while Muttley's is from George Thomson's Scottish Airs (no. 66, 1799), which Burns had sent him in a letter. Both versions are included in James Dick's The Songs of Robert Burns (1903; rpt. Folklore Associates, 1962, pp. 208-209) and Donald A. Low's The Songs of Robert Burns (Routledge, 1993, pp. 311-312). As is well known, the SMM version was set to a completely different tune.
