The Beatles - Everyday Chemistry

[United Hope]

The album was accompanied by a story written by an anonymous person under the pen name "James Richards". Richards describes meeting a man named Jonas who lives both in a parallel universe in which the Beatles never broke up. Jonas and Richards both discussed their enjoyment of the Beatles, and just before leaving the parallel universe and travelling back to his own, Richards stole a cassette tape containing one of The Beatles' albums from that imagined timeline.[4] Richards denied that the album was composed of mashups, reasoning that "even though in the alternate universe the Beatles hadn't broken up, that didn't mean their future music ideas disappeared."[5]
