I saw this on my local radio board and was surprised it hasn't turned up here yet. To celebrate the 30th anniversary of the Beatles Anthology collection, Apple will be putting out a 4th disc containing some remixes and at least a baker's dozen of unreleased supposedly never-before-heard demo tracks. 

There will also be an updated special on Disney+.

The new album is due in November.
