Another intriguing element of the film is how it captures McCartney in creative mode during rehearsals for the Madison Square Garden concert, breaking in a then-new band and work-shopping songs he’d only recently written and recorded (specifically “From a Lover to a Friend” and the makeshift anthem “Freedom”). For all the available footage that exists of McCartney down through the years playing music, far less shows him actually working on it.
Unfortunately such moments are all too rare and disjointed within the overall presentation. McCartney's compassion and selflessness are indisputable. The manner in which Maysles attempts to portray this ostensibly poignant experience, however, just doesn't come across.
