What if we all start chanting "We want John" before the set, and it won't be rude to Josh, because John and Josh used to play together anyway so they would just have both of them on guitar? Josh is like Johns padawan. John will heed our call, and it will be coachella that brought all of them back together, and then they will be awesome. I have no problem starting the chant, just need some followers. Thanks
Edit: John has teleportation powers for those of you wondering how he would get there in such a short amount of time.
