The Twelfth Album
"The Twelfth Album" is an alternative history short story by Stephen Baxter, first published in "Interzone" in April 1998. It is about an imaginary twelfth album recorded by the Beatles, called "God". The album features songs that were written and recorded as solo projects by the group's members in reality, but in a parallel universe where the Beatles did not split up following the release of "Let It Be", resulting in these songs being recorded by the group. In the universe where it was recorded, the Earth was apparently destroyed by a hail of comets, which  shocks the two middle-aged men who find the album in their deceased workmate's room on board the docked Titanic Hotel in Liverpool. In reality, the Beatles did release twelve albums, thirteen if "Magical Mystery Tour" is included. The story ignores one of them, "Yellow Submarine", because it is considered by the characters more a George Martin score than a Beatles album, and the other, "Magical Mystery Tour" was not an album in the United Kingdom until 1976.
