In fairness to Elton John and as you'll see yourself in the video, they did get a bit handsy during his performance and it undoubtedly gets a bit distracting.
The singer was playing one of his residency shows in Caesar's Palace, Las Vegas when the incident occurred, and happened as he was playing his 1973 hit, Saturday's Alright (For Fighting).
Usually, audience members are invited up on stage during the song - but after storming off the stage when one too many fans tried to get him to slap his hands - John said he wouldn't be doing it again. "No more coming on stage during Saturday Night," John shouted after returning to stage after storming off it. "You f*cked it up!"
Here's the video in question.
