On a recent, 2006, CD of Robert Tannahill songs the tune 'Donald Couper' is wrongly attributed to him. It was printed in Herd's collection in 1776 when Tannahill was two years old. The compiler confused it with a song called 'Hey Donald! How Donald' printed in the same volume of R A Smith's collection, 1820.
The same compiler incuded a song of mine in a collection of Burns'! It's advertised on the web as 'includes the tracks A Man's a man for a' That, The Lovely Lass of Inverness and Glencoe' (mine).
