Sad but true: It’s been 44 years since the Beatles last performed together on the rooftop of their Apple studios.

Throughout the show, which ran for more than 300 performances Off-Broadway, mop-top look-alike, sound-alike musicians—most alums of Beatlemania—perform songs from all eras of the Beatles’ career. Twist and shout to Rain on April 19.
