When I was young and had more spare cash than bringing up a young family leaves me now, I went to several Dave Burland concerts (mid-to-late 70s). In each, he sang a song called (if memory serves) Mythical Kings and Iguanas which he attributed to Dory (Dorry? Dorrie?) Previn and which I've never come across before or since.

Anyone know the words, tune, or anything about it or her?
