To be fair Robbie Williams, Kylie, Elton and Adele wouldn't be big misses. I am not a fan of their music. Elton did have a handful of good songs, but he's past it now and his mobility is not good. We have so many good artists over the decades, the planners could have done better I'm sure.Loads of the other names turned it down apparently. Adele, Elton, Ed Sheeran, Harry Styles, Robbie Williams, Kylie.
They all said no
