I believe I do have a timeline of events that you might find informative.
At Uncle Newt’s funeral, Jerry gives a eulogy in the form of a poem that he has composed about Newt.
In the poem, Jerry tells the audience of the years he spent living with Newt during the war. It was there that Jerry first started writing rhymes, for which Newt would pay him a ha’penny each (on condition that they scan).
He praises Newt as a teacher, storyteller and friend, before concluding with the lines:
Well, since you ask me for a toast…
O Nightingale! O Uncle Newt!
