Prior to his own secret performance at the event, Yorke joined Portishead during their headline gig for a rendition of The Rip.

Yorke then performed an unannounced solo set in the early hours of Sunday (19Jul15) that included songs A Brain in a Bottle and Black Swan, along with two unreleased tracks, reports.

The festival's woodland stage has become known for hosting secret gigs by big artists, and singer Ed Sheeran performed there on Friday night (17Jul15).
