Duncan sang this song of his own composition upon request during a recording session in Auchtermuchty, Fife, conducted by John Niles and members of his research team. Williamson had composed it decades before on the basis of his personal experiences on the road. He sang it shortly after singing "The Hawker's Lament," another of his compositions based on his life as a Traveller. "The Tramp and the Angel" is representative of Williamson's acceptance of sentiment as a core factor in popular song and, indeed, in human society.
Tobar an Dualchais includes two recordings of Duncan Williamson singing this song to Linda Williamson in 1976 (track IDs 28969 and 30879).
