KEY POINTS:
John Lennon's handwritten lyrics to Give Peace a Chance, written in 1969 during the legendary eight-day bed-in protest for peace, will be auctioned in London.
Christie's says the Beatle gave the sheet to 16-year-old Gail Renard during his bed-in with Yoko Ono at a hotel in Montreal.
The document is expected to bring up to US$600,000 ($777,000) at the July 10 London auction.
