<HTML>Actually, for somebody who doesn't know the tune, that's pretty good. For those of you (i.e. everybody except me and Sarah) the original is that classic ditty 'The Hippopotamus Song' (aka Mud, Mud, Glorious Mud) by Michael Flanders and Donald Swann, who were a sort of comic cabaret act who flourished in the 1950's and '60s.
My favourite Flanders & Swann song, though, is "Have Some Madeira, M'Dear" - you can see the lyrics at [
ion.le.ac.uk] although it omits the leer of "All unperforated!" that Flanders would insert after 'stamps'.
I was going to do the Hippo Song, but since I've been beaten to it I may try another one of theirs ... watch this space.</HTML>
