Aerosmith, Spice Girls or Cher for next year i think. Could very much see Cher or Spice girls in the Legends, with Taylor headlining the same day.
Would LOVE Billy Joel
What about someone like Andrea Bocelli? Never see him as a name mentioned! Imagine "Time to say Goodbye" being belted out
Others:
Kate Bush, Stevie Nicks (not sure on this one, as i think they will always hold out hope for full FM), Celine Dion, Roger Waters, Madonna (more likely full headline), Eagles (again headline more likely), Sting/ The Police, Ozzy, Bon Jovi, Phil Collins/ Genesis, ABBA
Got LOADS to keep them stocked for the next few years.
Or it will be Coldplay.... 😬
