I believe I do have a timeline of events that you might find enlightening.
Newt tries to convince his father, Patrick, of the merits of appearing on Desert Island Discs to promote a new book that he has written.
Patrick is very sceptical of the idea. His view is simply that the book is available for purchase and if people want to read it, they can do so.
Gally informs her parents, Patrick and Lettie, about the plans that she and Susanna have to tour the country as a musical act.
Her parents are hesitant, but are somewhat reassured when Gally tells them that Susanna has recently married a Captain Noone and that he will be travelling with them.
Gally’s brother, Newt, has been on the sidelines of the discussion. When their parents withdraw to discuss the matter, Newt asks Gally more questions about Susanna’s supposed husband.
Newt deduces that Captain Noone is a ruse. He tells Gally that the play on words with ‘no-one’ is not as subtle as she might think it is.
Gally tells him that it is too late to change the name from Noone, not least because she and Susanna are planning to rename their act ‘Midnight & Noone’.
The two discuss Gally’s new stage name of Midnight, agreeing that it is better suited than Nightingale given Gally’s low voice. This gives Newt an idea for a song in which Gally would play the part of a man who impersonates birds.
The Nightingale family are celebrating Christmas with a family friend, Monty James.
Patrick opens a Christmas cracker. He reads the joke, but sets his hat aside without putting it on.
His son, Oswald, and daughter, Gally, both protest that he should wear the hat. Even his wife, Lettie, points out that Mr. James is wearing the hat that he won from his own cracker. Patrick is unmoved and does not wear his hat.
Oswald opens his cracker next and is excited to find a kazoo inside. After requesting permission from his father, Oswald attempts to put on his own hat, but it rips as he is doing so.
Gally blames the rip on the large size of Oswald’s head, but suggests that Oswald should take their father’s unused hat. Patrick refutes the idea, saying that Oswald should have taken better care of his hat.
Seeing an opportunity to lighten the mood, Mr. James seizes Patrick’s hat and rips it. The family laughs as Patrick then rips Mr. James’ hat and Gally rips her mother’s one.
Patrick describes this round of hat ripping as “fun in its proper place”.
As the laughter dies down, Gally tells Oswald to let their dog, Toby, out.
At the end of the meal, Patrick reveals to the children that Mr. James is known for his ghost stories, and that he has kindly consented to tell them one now.
Patrick appears as a reluctant guest on Desert Island Discs. He is short and dismissive when asked questions and denies any interest in music.
His first choice of record is titled Strangers on the Shore, which he chose because it concerns the seashore as you might find on a desert island.
Patrick’s next choice for Desert Island Discs is a sound effects track depicting the sounds of a desert island, which he says he wouldn’t play anyway.
Patrick’s final choice for Desert Island Discs is By the Sleepy Lagoon, once again following his literal desert island theme.
He declines to choose a luxury to bring with him, but then surprises the host by choosing The Tale of Mrs. Tiggy-Winkle by Beatrix Potter as his book.
When asked why, he simply states that it is his favourite with no further elaboration. The host sighs and thanks him.
