My Dad studied medicine in Glasgow, Scotland and came home with the song before he himself went to war, as a US Captain. Years later, he was in the audience of the Tonight Show and they asked if anyone in the audience could sing a song that no one else knew. Dad got up on stage, sang My Wee Gas Mask, and won the prize. No one in the studio that night knew the song. He had taught it to me when I was very a very little baby boomer. I had forgotten the words. Thanks so much for writing them down. The Scottish version is the one he sang.
