I just wandered if there are any other verses to this song the origins are unknown to me

Iwanted to go on the stage
well soon my ambition was gotten
as i stared down on the audience
through the hole in the elephant bottom

It's dark and as damp as the mines
the smell it is putrid and rotten
but you don't expect O de Cologne
from the hole in the elephant bottom

hitler invaded with planes
he had great big bombs and he dropped them
some ran for the shelters, I know where I ran
up the hole in the elephant bottom

there's pockets all round the insides
for bottles of brown if yo got them
the audience laughs when I blow off the froth
through the hole in the elephants bottom

I courted a fair pretty maid
my mates they say she will drop em
but when she did it was nearly as big
as the hole in the elephants bottom

The last verse seems a bit barrack room and might have been added later.
