The makers of a movie about the Glastonbury Festival are appealing to fans for video footage of David Bowie, The Smiths and Marc Bolan.
The Glastonbury Festival has grown in popularity over the years
The festival's highs and lows are being recorded by director Julien Temple for the film, to be released in 2006.
Producers are hoping festival-goers caught some of the highlights of the 34-year-old event on video.
Bowie's 1971 performance and Primal Scream's 1992 appearance are among those being sought.
Marc Bolan - 1970
David Bowie - 1971
The Smiths - 1984
Primal Scream - 1992
Bob Dylan - 1997
The - as yet untitled - film secured funding for a cinema release last month and was launched by Glastonbury guru Michael Eavis.
It charts the history of the legendary festival since Eavis sold 1,500 tickets to watch Marc Bolan perform on his dairy farm in 1970.
Six hundred hours of footage has already been collected, but production company Root House Nitrate is looking for more.
Mr Temple, who directed The Great Rock 'n'Roll Swindle, the 1980 film about the Sex Pistols, told the BBC News website the five performances he was looking for were all seminal moments from the festival.
"David Bowie is the interesting one. He played at the first proper festival in 1971 at 4am," he said.
Producers are hoping to capture personal stories in the film
"He wasn't famous at the time and that performance is almost the Holy Grail of festival acts.
"I was actually at Glastonbury when he played. Someone woke me up saying 'you have to check this guy out'.
"He was absolutely amazing and I'd love to see any footage from a personal point of view."
Mr Temple added that Bob Dylan insisted that the BBC removed their cameras from the stage during his 1997 appearance while the performances by Primal Scream and The Smiths were both considered legendary.
And he admitted that finding footage of Marc Bolan's 1970's appearance would be "extraordinary".
"I have seen some footage from behind-the scenes, so we know there were cameras there, but there is nothing of his actually performance," he said.
Phil Shepherd, one of the film's producers, told the BBC News website it was important for Glastonbury-goers to be involved in the making of the two-hour-long feature film.
"Part of the concept is that as many people as possible who have attended the festival should contribute," he said.
"There is huge value in stuff filmed by non-professionals.
"We have already received some wonderful stuff but we are still looking for more - especially for footage from festivals before 1989."
Mr Temple added that there was a lot more to the film than just the music.
"I've always felt that the event was central to English culture and it explains so much about our identity... it is a meeting of all different tribes and types of people.
"That is as fantastic as the music on the main stage."
