In a recording of John Kirkpatrick playing the Border Morris tune "Om si the gom" (whatever THAT may mean) there is one verse of a song.

There was a little nigger and he got no bigger
So they put him in the Wild West Show
He fell through the winder (window) and broke his little finger
And he couldn't play the old Banjo

When my mother heard us perform this some years ago, she remarked that she knew it as the Lord Mayor's show, not Wild West. It must be part of an old song, does anyone know any more of it?
