Kylie Minogue could headline next year's Glastonbury festival, event organiser Michael Eavis has said.
Kylie Minogue underwent surgery for breast cancer last May
"Kylie is coming back hopefully. Her people are quite confident. She really wants to do it," said Mr Eavis.
The singer had to pull out of last year's festival after being diagnosed with breast cancer.
Mr Eavis was speaking at the London launch of a documentary film about the 35-year-old event, told through the eyes of festival-goers.
"Kylie doesn't fit the Glastonbury festival image with Neighbours and all that razzmatazz, but her shows are so theatrical they are almost like a circus in a way, which really fits in with Glastonbury," added Mr Eavis.
The festival is taking a break this summer, but is due to take place again in 2007.
Faithless and Rolf Harris were among the musical acts at the screening who have performed at Glastonbury.
It had its first UK screening at Street, Somerset, close to the festival's home.
Director Julien Temple, whose previous credits include The Great Rock 'n' Roll Swindle and Absolute Beginners, began work on the film in 2002 when Eavis decided to have a permanent record of the festival put on film as its future was in doubt.
Film crews then visited all the festivals between 2002-5 and collected 1,500 hours of amateur and professional footage.
In a statement on the Glastonbury website, Mr Eavis said Temple had done a "brilliant" job.
"The most important thing is he hasn't left anything out," said Mr Eavis.
"He's really captured the festival - the good times and the bad times, but most of all, the many important things that the festival has come to represent over so many years."
1,500 hours of Glastonbury footage was collected for the film
The festival started in 1970 when Eavis sold 1,500 tickets to watch Marc Bolan perform on his dairy farm.
It has gone on to become one of the biggest annual events of the UK music calendar, attracting top bands and more than 100,000 fans each year.
Among the acts to feature in the film, released across the UK on Friday, are The Velvet Underground, Primal Scream, Coldplay, and Bjork.
"Making this film has been very similar to being at the festival," said producer Robert Richards.
"It's been an intense, life-changing experience, and once all the washing-up has been done, full of happy memories," he said.
