Following on from my search for the 1970s Surrey-based duo "Trousers" (see thread, "Lost Trousers") I am now searching for a song they used to perform that was called The Walrus Song, or perhaps just The Walrus. I have no idea if it is traditional or self written - though I fear the latter in which case it is almost certainly lost for ever.
It was pretty bawdy, and I have no recollection now of the words, though I'd recognise it instantly if I saw/heard it.

Can anyone help?
