Many have been moved by this song even without knowing quite what all the expressons mean.The emotion is somehow communicated .
I offer here a glossary of dialect terms given in the "Modern Folk Ballads" edition of "Pocket Poets"
In this anthology, the word "bastards" is used where "swaddies" appears in the DT version.

pipie=pipe major; dozie=sleepy; fey=acting in a strange manner, as if having a presentiment of something out of the ordinary,or of death; unco=strange, unusual; chaulmers=rooms; kyles=straights; smoor the wiles=obliterate your fascination(literally,'smother'); drummie=drum major; beezed=polished (beezin= spit and polish); shielin=hut; byres and bothies=cow sheds and cottages; shebeens=boozers, drinking dens.

I sometimes anglicise verse two thusly-

The drumie he's polished the drummie he gleams,
He cannot be seen for his webbings bright sheen,
He's beazed himself up for a foto of him,
To leave with his lola his dearie.

I would then give "all the bricht chaulmers are eerie" as "The buildings stand empty and eerie"

Hope this is of some use to someone, somewhere.
Keith.
