So as we've already heard, GNR apparently are heavily rumoured to play glastonbury next year (https://www.somersetlive.co.uk/whats-on/music-nightlife/glastonbury-2023-line-up-headliners-7697791)
The ticket sales for the festival start on nov 3rd. Surely they will be announcing at least some of their headliners by then, right?
