The Don't Stop hitmakers thrilled crowds at the annual music event after widespread speculation left festival-goers fearing the group would pull out following the previous cancellation of a number of gigs due to illness.
Frontwoman Stevie Nicks proudly told crowds, "This is show (number) 90. This is the first festival that we have done... Now let's party."
Other stars to take the stage on the last day of the festival included Pharrell Williams, who paid tribute to Jimi Hendrix by instructing the audience to point to the sky as he performed America's national anthem, The Star-Spangled Banner, and Hendrix's hit Hey Joe.
A further tribute to Hendrix came in the form of a world record attempt during which revellers wore masks featuring the rock legend's face in a bid to score the most people in one place wearing a mask.
Irish singer Imelda May also revealed during her set that she had lost a loved one two days before the festival and she performed her track Inside Out as a tribute.
Other acts to perform during the three-day event included British pop stars Ella Eyre, Jessie Ware and James Bay, disco veterans Kool and the Gang, rockers Blur and dance stars The Prodigy.
