As far as we know, the song goes like this....

Where be that blackbird to?
I know where he be,
He be up yon wurzel tree
And I be a'der he

And he sees I
And I see he
Buggered if I don't get 'im

With a gurt big stick I'll knock 'im down,
Blackbird, I'll av ee

Lalalalalalaa, lalalalalalaa, 'owz your father?

ALRIGHT!
