Clinching a Sale (1930)

Harry Richman stars in this bizarre comedy musical short. I say bizarre because he is a door-to-door broom salesman who sings to make sales. However, his potential sale (June O'Dea) is not an easy one, as she complains that the previous door-to-door salesman was more impressive...so Richman brings out a trio to accompany him. But this lady is no pushover...so what will he need to do to clinch the sale?
