A box set of previously unreleased recordings and studio chat by The Beatles including early hits and cover versions is to be released later this year, their record company says.
The tracks from radio broadcasts at the British Broadcasting Corporation (BBC) in 1963 and 1964 include 37 performances which have never been issued before now and 23 tracks of conversations featuring the Fab Four.
The album, "On Air - Live At The BBC Volume 2", is a follow-up to a similar box set released in 1994 and will be available from November 11, Apple and Universal Music said in a statement on Friday.
It includes two songs which were never recorded for their record label and which have not had official release, "Beautiful Dreamer" and Chuck Berry's "I'm Talking About You."
Beatles fans first noticed the box set was coming when there was a posting on the website of an offshoot of music company Universal in the Philippines last month, but the full details of the recordings were not confirmed until now.
