John Mearns was recorded by the BBC singing this song in February of 1950 (BBC recording number 14404), according to the Roud Folk Song Index. That was the recording I referred to earlier. He was recorded at various times during the early '50s, his repertoire including The Barnyards o' Delgaty; The Bonny Lass o' Fyvie; Drumdelgie; The Guise o' Tough; Johnny Sangster and other standards of the Northeastern tradition.
