I post this video because I have been in this exact situation.
No, I’m not the obsessed fan pulling a performer off the stage, but I am/was the security person responsible for keeping order at major entertainment events.
In the video you’ll see Beyoncé’s performance at Morumbi Stadium in Sao Paulo, Brazil yesterday. Midway through her rendition of “Irreplaceable,” a young man gets caught up in the moment and makes a bad choice.
Beyoncé on the other hand, handled the situation in stride.
Now, back in my day – I would have had the fan with his arms pinned behind his back and briskly escorted outside of the venue.
