Tom Waits is the best one, though can't blame the festival for that one, dude doesn't play anywhere.
Wonder what kind of spot he would do? Legends spot? Part of me thinks he should be high as possible being, you know, Tom f**king Waits and a strong contender for the best musician in human history (at least for me). But on the other hand, he notoriously doesn't have any hits or singalongs (and the few he does have - mostly because other artists covered them - he never plays), and this will surely be the weirdest and most experimental legend slot ever lol.
