Following on from the crossover, Jon and I take a deep dive into the "Long and Winding Road" Documentary (or at least the version that has managed to walk out of Apple).      Very much the bones of Documentaries to come, ranging from "Compleat Beatles" to "Eight Days a Week", "Get Back" and its own offspring - "The Beatles Anthology".     Cross your eyes, and you'll drop into the Rutles-verse as well.
