OK let's start at the beginning When fishes roamed the sea They swam around before anything else In ten million years B.C. Then one day they decided To evolve into vertebrates And a few came out of the water And got drunk to celebrate Soon, well when I say "soon" I mean A couple million years They evolved into various quadrupeds With legs and things and ears And about a trillion aeons later They went all civilised And built lots of bombs and council flats That reached into the skies The moral of this tale, you see We are descended from the fish And if we progress much further We'll put our lives at risk We're starting to destroy ourselves With pollution, war, and greed When food and sex and water Is all we really need When "sink or swim" is the choice you get You cannot swim forever You need support to keep you alive Us fish must swim together!
