A draft letter from John Lennon, written in 1971, is set to be auctioned on December 5, 2024, with expected bids ranging between 100,000 euros and 150,000 euros ($A162,618-$A243,928).

In the letter, Lennon invites Eric Clapton to join a new supergroup, listing other musicians he had approached, including Klaus Voormann, Jim Keltner, Nicky Hopkins, and Phil Spector, to create a powerful collaborative sound.

Lennon emphasized a fresh approach to touring, wanting to avoid the pressures he experienced during his time with The Beatles.

He proposed a unique idea of renting a 'big ship' with a film crew to document their music-making process, suggesting they rehearse and record while traveling.

Lennon reassured Clapton that there would be no pressure to join, focusing instead on creative freedom and the importance of Clapton's musical input.

He expressed admiration for Clapton's music and offered support, acknowledging Clapton's personal struggles without directly addressing them.

The letter reflects Lennon's vision for a new touring experience, including ambitions to perform internationally in countries like Russia and China.

Despite Lennon's enthusiastic pitch, Clapton ultimately declined the offer to collaborate on this new project.

The letter, which includes multiple edits and markings, showcases Lennon's evolving musical style during his early post-Beatles career.

The draft letter serves as a rare glimpse into Lennon's personal communication and his vision for collaboration in rock history.

This auction coincides with heightened interest in Beatles memorabilia, particularly with the recent release of Martin Scorsese's documentary 'Beatles '64'.
