A Double Wedding?

After confiding her doubts about marriage to Sarah, Diana has a raucous hen night with male strippers whilst Tom's stag night is a very staid affair.
The befuddled Dennis Sparrow is to conduct the two wedding ceremonies separately but due to a double booking involving a funeral, a double wedding is on the cards after all - despite Marion's efforts to sabotage Tom's marrying Diana.
She need not have worried because, whilst Jane becomes Mrs. Harvey Baines, Tom and Diana happily agree not to marry after all but to live in sin.
