Yorick appears to have preached Le Fever's funeral sermon. He had a habit of making notes on sermons—this one's really good; this one's only okay; this one will suit any occasion. Some of his notes are confusing, because he uses musical terms that don't make sense in a theological context.
Anyway, the sermon upon Le Fever was one of Yorick's favorites: he wrote "Bravo!" at the end (although very small, so as not to appear to be bragging. Also, he struck through it later on).
