If you can find the old Springthyme label LP 'Shores of the Forth' from the mid 70s, you'll hear John Watt singing his own song on the subject.

If it's survived, there was also an insert, with drawings by my old friend Lynn Breeze, giving all the words on the LP- I don't know if it's on CD nor whether the words survived the transfer but you can check this on the Springthyme website.
