Love this place - thanks for making the link, Dave, it's solved a couple of mysteries (for me anyway).

Given that the true title is "The Coppers' Song", the composer, as I had suspected, was Hamish Imlach.

According to Hamish's discography, it can be found on record as follows:

Hamish Imlach - The Definitive Transatlantic Album (Castle Communications, 1997) ( includes: It's Better In The Dark; Cod Liver Oil And Orange Juice; Johnny O'Breadislee; Erin Go Bragh; If It Wasn't For The Unions; Foggy Dew, The; Copper's Song, The; McPherson's Farewell; 37 Bus, The; Jean Harlow; Clapped Out Motorcar; McGreggors, The; Anthony Riley; Beer Is Best; Little Maggie; Goodbye Booze; Calton Weaver, The; Clive's Song; Cuckoo, The; Kilbogie; Bluebird; Jenny Jenkins; Travelling Rhythm)

Looks like a CD to me, and, if so, is one that will shortly join my collection.

Thanks all

Alan
