This song, known as the Coffeepot Song in the database, intrigues me. Where's it come from?

John Bartlett posted the following in another thread:

Graham Pirt, I note you know something about "Proper Cup of Coffee", which I've been looking for (info, that is). Could you post it to me at Rika_Ruebsaat@sfu.ca? Thanks a million

Apparently, he's wondering, too. Can anybody tell us a story behind this great song? On their Voices of Winter CD, Priscilla Herdman, Anne Hills, and Cindy Mangsen do a great medly of this song with "The Frozen Logger." Great CD - and it's in season again.
Thanks.
