Absolutely awesome! I thoroughly enjoyed part 1. It was joyful to watch the band creating. Even though you could see the tensions that led to their breakup later that year.
The best part was seeing them developing songs. For example, seeing George bringing in "last nights songs" I Me Mine and For You Blue. Paul working out lyrics for Long and Winding Road. Glyn Johns helping with the arrangement for Let It Be.
You really gained an appreciation for how they worked together.
