Diana Ross is the first artist announced for Glastonbury 2020, the 50th anniversary of the British music festival.

Ross will be performing on the final day of the five-day event. She will be performing in the “legends spot,” the festivals most revered slot. In previous years, this slot was filled by artists such as Paul Simon, Dolly Parton, Lionel Richie, and most recently Kylie Minogue. According to the BBC, last year 3.2 million people tuned in to watch Kylie perform.

Tickets went on sale on Oct 6 and sold out within 34 minutes. Emily Eavis, festival co-organizer, and daughter of its founder Michael Eavis, posted on Twitter that a record-breaking 2.4 million people were vying for the 135,000 passes available.

The Supremes singer, whose hit singles include “Endless Love” and “Ain’t No Mountain High Enough”, took to Twitter to share her excitement.

As for the rest of the lineup, there are a few conjectures going around, like Taylor Swift, who has a mysterious Glastonbury-shaped gap in her tour schedule. Other favourites include Paul McCartney, Madonna, Fleetwood Mac, and Oasis.

For the festival’s 50th anniversary, Michael and Emily Eavis will be releasing a book that covers years of behind-the-scenes festivities. The book will include features from artists including Jay-Z, Dolly Parton, Adele, Noel Gallagher, and Chris Martin.

Stay tuned for the full lineup release, it’s going to be monumental.
