I was cleaning up a folder of mp3 songs about whales and whaling and encountered one labeled "Leviathan Reynard". I wasn't sure what that meant so I started searching which brought me to this thread where there wasn't a whole lot more detail. Further searching did lead to more information. "Leviathan" was written by Mal Eden. Eden was a member of the UK band Reynard. Leviathan is on their album Green Anthem (Grapevine – Grv 132)released in 1979. Band members were Eden, Andy Wood, Dave Rycroft and Paul Pearse. I also found a couple Green Anthem albums for sale in the UK for $70-150.
