Elton John stormed off stage in Vegas during “Saturday Nights Alright For Fighting”. Elton invites fans up on stage to surround his piano when he sings that song. A month ago, a fan threw Mardi Gras beads and actually hit Elton John in the mouth so hard that he actually stopped the show. This time it was a fan getting a little grab at Elton and thanks to that person, nobody will be allowed to go onstage anymore or as Elton put it, You F**ed Up!
