The single, titled "Now And Then," was written and sung by John Lennon and was later completed by other band members, including Sir Paul McCartney and Sir Ringo Starr, decades after the original recording.
The track is based on a Lennon demo recorded in the late 1970s at his home in New York's Dakota Building. Advanced technology was used to extract and isolate his voice from the demo. This new version of the song has been eagerly awaited by Beatles fans.
The event in Liverpool allowed 200 fans in the home city of the four Beatles members to be among the first to purchase a copy of the single, available in clear, blue, or black vinyl. The release of the song was accompanied by a double A-side with the band's 1962 debut single "Love Me Do," and it features cover art by US artist Ed Ruscha.
The director of "The Beatles: Get Back," Peter Jackson, expressed his excitement at being involved in the creation of what is being referred to as the "last Beatles record." He discussed this on the BBC Sounds podcast "Eras: The Beatles," narrated by actor Martin Freeman. Additionally, New Zealand filmmaker Peter Jackson directed the music video for the track, which was set to be released at a later time.
