There were plenty of reasons why Sir Paul McCartney's performance at Glastonbury on Saturday was momentous.
Besides being the music festival's oldest solo headliner ever at the age of 80, McCartney also got a unique reunion with a former Beatles bandmate.
McCartney sang "I've Got a Feeling," with a video of John Lennon projected on screens.
The video came from Peter Jackson's footage from the "Get Back" docuseries.
"I know it's virtual, but there I am singing with John again," McCartney said. "We're back together."
