Insisting that she is the perfect person to play the lead in Emmet's musical, Hyacinth interrupts Emmet's rehearsals at the church hall in order to show off her musical talents. Then, she decides to hold a 'bon vivant buffet' at Violet's house so that she may show off her singing once again in front of Emmet, Liz, the vicar and his wife.
- A "luxury barbecue" at Violet's house looks like being a disaster because Bruce and Violet keep having violent arguments. Hyacinth organises a sing song in an attempt to take everyone's mind off their hosts' battle. Later, Hyacinth goes along to a rehearsal of "The Boy Friend" to offer her services to Emmet.
