Most people think that the only instrumental track they released as The Beatles was the tune "Flying", from the Magical Mystery Tour film. It was released in the U.K. on the extended player & in N. America on the album of the same name at the end of 1967. However, they also recorded an outtake version of the tune called "Aerial Tour Instrumental that wasn't released.
They recorded "12-Bar Original" in 1965, that wasn't released until the 1996 "Anthology 2" album.
They recorded "Cayenne" in April '60 when still known as "The Quarrymen", that wasn't released until 1995 on the "Anthology" album. It features Stu Sutcliffe playing a sloppy bass track.
They recorded "Cry For A Shadow" on 22 Jun. '61 in the gym of Friedrich Ebert Halle in the Harburg district of Hamburg, Germany while performing as "The Beat Brothers" in support of Tony Sheridan as he recorded an album. This was just days after Stu Sutcliffe quit the band. It's one of only two officially released Beatles
singles that has Pete Best on drums when it was released in 1964. It also appears on the 1995 "Anthology" album.
In future, if people insist on posing "questions", it'd really be nice if they got their facts right.
