It's one of Nancy Nicolson's songs, and in her book - "They Sent a Wumman"! ISBN 978-1-907676-86-4. On page 120. Maybe one of your pals will have a copy, or well worth buying one? She is usually happy to share her lyrics, but need to ask first!
It is also track 16 on a CD of hers called "Rhyme and Reason" - one of several "bonus tracks" added to a re-mastering of a 1990 cassette recording of her songs. PM me if you get stuck.
