To pass some time until an announcement, here's a guess at the top end of the main stage.
Friday - Coldplay, Stevie Nicks, PJ Harvey.
Saturday - Dua Lipa, Pulp, Avril Lavigne.
Sunday - Stevie Wonder, Olivia Rodrigo, Paolo Nutini, Shania Twain.
I did have Stevie Nicks and Olivia Rodrigo the other way around, but two acts named Stevie being back to back sat wrong with me.
