David Bowie (2000)
First performing at Glasto on its second year in 1971 - back when it was free to get in - Bowie returned to headline the festival in 2000 to a rapturous reception. Afterwards, event founder Michael Eavis labelled it the best Glastonbury ever.
He was reportedly asked to play for 2010's festival, but the appearance would have been Bowie's first concert in six years, since he suffered a heart attack while on stage in 2004. The 66 year-old is back on top form, as his new album The Next Day shot straight to number one earlier this year.
