"A Man's a man for a that": Robert Burns borrowed one of his lines and the tune from an older song in Hogg's 'Jacobite Relics', II, 1821, "Though Geordie reigns in Jamie's Stead". The tune is in the Northumberland Vicker's MS, c 1772, as "For aw that and aw that". A copy of the song c 1750, is in NLS MS 2910 with the heading "A New song Tune Lady Mackintosh's Reel". For early copies of the tune under that title (and yet another) see the Country Dances 2 file on my website.
