For British acts (or acts with close ties to the UK) then headlining Glastonbury will always be something people want to do.
You can earn peanuts at Glasto and silly money in stadiums - happily doing both in the same year.
For global superstars it does not hold the same appea.
I,d be very nicely surprised if they confirm NIN, it, s a great update, big leap in the quality of lineup, .let,s wait to be official.
I will settle with NIN, Vampire Weekend & Manic Street Preachers, just for asking😀
