Green Day drummer Tré Cool has told NME the band would be open to headlining Glastonbury, calling it "the last great festival that we haven't done." The comments came in an interview promoting Nimrods, a new coming-of-age comedy inspired by the band's early touring years, in which Green Day appear as themselves and act as producers. Despite headlining major festivals including Coachella, Reading & Leeds, Lollapalooza and Download over the years, the trio have never played Glastonbury's Pyramid Stage.

Cool said he simply follows the band's schedule rather than being involved in booking decisions, joking "they're not really calling the drummer." Frontman Billie Joe Armstrong previously attended Glastonbury in 2019 to watch his son's band SWMRS perform. Elsewhere in the interview, Cool addressed the long-rumoured "American Idiot" film, saying plans resurface periodically but the band remain focused on new work rather than looking back. Glastonbury, which took a fallow year in 2026, returns from 23 to 27 June 2027, with organisers yet to confirm headliners despite rumours linking Madonna to the bill.
