Several sources credit the author as Tim Joseph with the date as 1975. One describes it as a poem.
It is published in Issue 2: May 2003 of The Griffith University Maths and Physics Association Magazine with the following preamble:
"The article written here came from "Science" Volume I, Number II. Science was a monthly journal produced by the Griffith University Science Association in the School of Science in the early 80's."
Correction the the lyrics:
The second line of the second verse should read:
"and objects at rest tended to remain at rest,"
