It is The Annual Staff Dance of A.F. Stobo & Co., Carpet Manufactures. During the first act, everyone arrives at the Hall, Lucille and Alan arriving together in his father's top-of-the-range car. Phil and Spanky spent the act drinking, lamenting Phil's job loss. Sadie complains to Miss Walkinshaw about Mr Curry stopping her on the way to the dance, and offering her a job as his cleaner.
