Back in the day, I remember going to a concert called edgefest. During the Green Day set. The lead singer of Green Day asked if anyone could play guitar. One fella ended up going up on stage, when they found he couldn't play guitar. He was asked to do his first stage dive.

No one caught him, but the air ambulance that came to pick him up.

Was years ago! Back in the day!

Here's a video of Green Day at edgefest, live from Vancouver, Canada.

This is where the story above from. But could give some insight.
