You can find the podcast called "Riverrun to Resurrection" explaining Pages 3.01 to 5.12 (annotations also on FW Chapter 1 above) of Finnegans Wake on Youtube.
The sources used to produce thie Notebook LM podcast provide a detailed exegesis of the opening pages of James Joyce's Finnegans Wake, specifically pages 3.01 to 5.12 (more details at finneganswakenotes.net). They meticulously annotate the dense, multi-layered language, identifying literary allusions, historical references, linguistic puns, and recurring motifs such as the Viconian cycle, the fall, and the dismemberment of Osiris. The texts also trace the origins of characters like HCE (Humphrey Chimpden Earwicker), showing how his various guises, from a primal builder to Humpty Dumpty, are interwoven into the narrative. Furthermore, the sources reveal the cyclical nature of the book, where the beginning mirrors the end, and explore how Joyce’s personal life and experiences, including his family and fears, are embedded within the intricate wordplay and themes of regeneration and transformation
