A woman from London is set to make a fortune when John Lennon's handwritten lyrics for the anti-war song Give Peace a Chance go up for auction this summer.
Gail Renard was given the lyrics to Give Peace a Chance by John Lennon
They are expected to fetch between £200,000 and £300,000.
Gail Renard was a student in Montreal in May 1969, when Lennon and wife Yoko Ono arrived to hold a "bed-in" at the city's Queen Elizabeth Hotel.
She and a friend sneaked into the hotel - Renard calls it a "Mission: Impossible" routine - and up to their door.
"Yoko answered and I asked if I could have an interview for my school newspaper.
"She graciously said yes. She asked us in, and I was suddenly face-to-face with John Lennon."
Renard and Lennon became instant friends, and he asked her to stay and help with the "bed-in".
"It was Alice in Wonderland," Renard says of the eight-day experience.
"I was a 16-year-old, with a Beatle who was my hero, and it was just a circus every minute.
"On the last day, John wanted to record a song," Renard recalls.
"We didn't know what it was at the time."
After recording Give Peace a Chance, Lennon gave Renard his original lyrics for her to keep.
These spent years hanging on a wall in Renard's study but were then moved for safety, ending up in a vault.
"I thought, this is ridiculous," she said.
"They should be out with somebody who can enjoy them, and they should be seen again."
Give Peace a Chance reached number 14 in the US Billboard chart
She also believes the song and Lennon's message have a particular resonance now.
"It's my way of thanking him, to get his message and his song out there again, and have people thinking about it and talking about it."
The piece is the highlight of Christie's rock and pop memorabilia auction on 10 July in London.
"Beatles lyrics, and particularly in John Lennon's hand, rarely surface on the auction market, so it's very much a unique opportunity," said Helen Hall, head of popular culture at the auction house.
Other items being sold will include a collage made by Lennon as a birthday card for Elton John in the 1970s, plus an amplifier played on stage by Jimi Hendrix.
