Chart stars past and present are attempting to recapture 10 hours which shook the world as they emulate the recording of the Beatles Please Please Me to mark its 50th anniversary.
In one mammoth recording session - the productivity of which would put some sluggish or perfectionist bands to shame - the Fab Four recorded almost their entire debut album.
In the space of just 585 minutes, which some bands may take to perfect the sound of a snare drum, the group recorded 10 tracks for the LP, as well as a leftover which was revamped for their next album.
BBC Radio 2 is celebrating the historic breakneck workrate which took place on February 11, 1963, by inviting a group of stars to work on one track each during a live broadcast throughout the day from Abbey Road's Studio 2 today.
Figures such as Mick Hucknall, Stereophonics, Gabrielle Aplin and I Am Kloot will be putting their own spin on the songs the Beatles recorded.
The original recording saw the band playing live renditions - save for a few false starts and mistakes - of the songs which formed the core of their shows, with little in the way of overdubs in the way bands record layers of instruments today.
The final track of the day Twist And Shout - held back to the end because of fears that John Lennon's already ailing voice could be wrecked if it was played any earlier - was captured in one take. When Lennon, singing topless at the climax of the session, had tried again he could barely sing so they stuck with what they had.
