Yep, Murray Schoolbraid's edition of Peter Buchan's Secret Songs of Silence - which is called The High Kilted Muse, has been published by the University Press of Mississippi.
Only available as a hardback as far as I'm aware.

Best English price that I could find was £44.31 from The Book Depository.
A pity that the two should be vying for customers.
