"Yesterday" is a 2019 film based on a story by Jack Barth and Richard Curtis, named after the 1965 Beatles song.

After recovering, he sings the Beatles song "Yesterday" for his friends and discovers they have never heard of the Beatles. After searching for the Beatles on the internet and finding the band's records missing from his collection, he realizes he is now living in a world where the group never formed.

He begins performing Beatles songs, passing them off as his own. Jack battles with his conscience and the concept of right and wrong as he gains worldwide fame, yet it is for for something that he really did not earn.

At a record launch concert two people who also recall the Beatles, approach him backstage. They tell him they know he didn't write the songs, but thank him, having feared the Beatles' music was gone forever. They give him the address of John Lennon, who, having never formed the Beatles in this reality, has survived into old age, out of the public spotlight. John, who has lived a happy life with his wife, advises Jack to pursue the one he loves and always tell the truth.

The Beatles were an English rock band, formed in Liverpool in 1960, that comprised John Lennon, Paul McCartney, George Harrison and Ringo Starr. They are regarded as the most influential band of all time.
