Lyrics:

'Whose side are you on?'
Said the spider to the bird
'Do we creep up on him as he sleeps
And string him up in my web?
Or do we swoop down and blast him
With your black and white slime bomb?
Trouble is I can't fly.
And my seventh leg is there to keep me symmetrical.'
And the surley bird opened his big beak and swallowed the spider whole
Seventh leg included.
He was a bird-eating spider in disguise
What a surprise
