Disney+ It is to Paul McCartney’s eternal credit that the former Beatles bassist has long nurtured the relevance of rock & roll’s most important band. He talks about the group – and his role in its sometimes contentious history – not with reverence but affection, sharing memories that memorialise the Liverpool quartet without rendering them an untouchable monument. McCartney participates in profiles, performances and documentaries, giving their youth and art from the 1960s a contemporary presence. “It was good, you know,” says McCartney with a sweet smile, as he and Rick Rubin listen to George Harrison’s acoustic guitar intro to And I Love Her.
