If you get a chance, go see the film "Yesterday." It's a funny and ultimately uplifting story about a struggling musician who has an accident during a mysterious worldwide power outage, and when he regains consciousness, he seems to be the only person on Earth who knows anything about the Beatles or their music. Google searches turn up nothing, no one knows a thing about them or any of their songs.
What happens after that is quite a story.
Well worth seeing.
I love happy endings.
