Susanne, I have the LP 'The Ettrick Shepherd' by the McCalmans, and I can't find any credits for Ian McCalman as the composer. The label just says (J. Hogg arr. McCalmans) on all the tracks, even those that are known to be traditional tunes. Do you have a CD version? Perhaps the notes are different for the CD. Not that I doubt your word of course! And I seem to remember from comments at their concerts that you are right - but it is nice to get the details right.

Anyway here is the tune. The McCalmans sing this as a duet, with the first verse of the 'Farewell' followed by the first verse of the 'reply' etc.
