The seriousness of his injuries is unclear.

ack! hope all is well

Hope he is okay, falling down is devastating enough for the elderly without it being off a stage.

I really hope he got out a "Fly, you fools!"

hopefully he didn't get seriously hurt

What's the man doing flailing around stage ledges, come on man be reasonable and perform sitting in a comfy chair.

It’s just like him to crowd surf.

Something something, "break a leg", something something.

Seriously though, I hope he's ok.
