Inspired por the film 'Yesterday' If tu woke up and no one but tu remembered the Beatles. What would tu do?

I would do everything I can to bring the Beatles into people's memories. I would not rest until the Beatles are remembered por everyone.

If any of the Beatles were still living, which I would assume they would be, I would try to find them, and I would beg them to mostrar the world who they are and help them to be remembered forever.

Oh, dear. My worst nightmare! First, I would try to make sure I wasn't just dreaming. Then, I would do everything I could to bring the Beatles back to people's memories. I wouldn't give up, ever.

This would be horrible and one of my worst nightmares ever. Anyways, I would try to find all the four Beatles and persuade them to go on another tour in order to gather as many people as possible and restore their memories of the band. I would not quit until the mission has been accomplished.

Wait - do we mean, "the Beatles existed but nobody remembers them" or, like the movie, "the Beatles simply do not exist now"? Because if it's the latter: first step, appropriate mourning period for the band that never was. Then... maybe I might just rewrite their story to have a happy ending, let everybody read that version of events and accept it as cannon? And then try and find the four Beatle members and introduce them to each other, because it's just not right if they never meet. Then I subtly guide them to the decision of starting a band, and the rest I leave to them....
