It's happened before wayyyyyyyy back in the distant past. Jump in a time machine and set the dial to 2015 and you'll see a band sub the pyramid who wasn't on the initial poster (or any poster for that matter)

Oops! This is my first Glastonbury, so I was not aware of that. I stand corrected, though I still think it is a good theory.

[Radiohead touring in 2016]

If I previously did not know that Radiohead was and band and read this thread for the first time, I would probably come to the conclusion that Radiohead was some kind of cult

Seriously though, the mental acrobatics you people are using to place Radiohead as the Saturday (sub-) headliner is astounding, and yet, you lack imagination. The Syrian National Orchestra is playing Glastonbury this year. On the Pyramid Stage: Syrian National Orchestra -> secret set with Radiohead ft. Syrian National Orchestra playing Radiohead's new album. Boom! Seems as equally likely scenario as Radiohead being a headliner or sub but not getting announced on the initial lineup poster.
