John Lennon's 1971 draft letter requesting Eric Clapton form a new supergroup with him is expected to fetch €100,000 and €150,000 at auction.
The late Beatles legend penned in the eight-page note that he was keen to recruit the 79-year-old guitar hero for a new musical project alongside Klaus Voormann, Jim Keltner, Nicky Hopkins, and Phil Spector, after they all had stints in Lennon and his widow Yoko Ono's musical collective the Plastic Ono Band.
