An on-site source said that the Radiohead frontman will perform later today (June 25), although it's not clear on what stage.
UPDATE: Gigwise now understands the performance will take place at 8.30pm on The Park Stage.
Radiohead and Yorke's producer Nigel Godrich has already been spotted on the festival site this morning.
The band's management company had not responded to an email request for comment when this story went to press.
