Murray, I don't know if you might be interested or not, but I just received a gift of a box of old 78 RPM records of Scottish folk dances and songs, which I am currently taping for my brother.
One of the records has additional lyrics to that in the DT for Dumb, Dumb, Dumb. I'll also have to check again on a previous thread to see if the recording of The Bonnie Wee Window is the same as your posting of the lyrics.
Would you like me to send a tape over of what I have?
