Julian Pilling quoted the verse from Bill Rossall (of Nelson) who remembered his father, a relative of Ernest Butcher, singing it in the 1930s.
Oh we're all down in the basement Where the mud splashes on the casement We've burned all our coal up and we are now using cinders If the bailiffs come for us, they'll never find us Because we're all down in the basement Where the mud splashes on the casement.
Butcher made a story of the song. In that part, the son of the family has grown prosperous and they live in a mansion and speak Standard English, but by the end they're back where they started, dialect and all.
