It seems The Beatles are releasing Anthology 4, 30 years after Anthology 1, 2 and 3.
They're teasing the release with a post on social media that's captioned, "Let's Gooooo!!!!!"
In November 1995, and March and October 1996, they released the the three-volume set, a collection of unreleased performances and outtakes presented in roughly chronological order. It was supported by an three-part ABC-TV special in November of '95 as well as a massive coffee-table book.
No releases date given yet.
