This is called the (something) Polka. The missing word is a district of London which I've forgotten.

There's been a body in the house
Since father passed away.
He took bad on Saturday night
And he went the following day.
Mum's pulled the blinds all down
And bought some cherry wine.
And she's put the tin
What the arsenic's in
At the bottom of the Serpentine.

I particularly love the Cockney pronunciation of house - 'aaahss'
