The Specials (well Neville Staples version) gig a few years ago in Sydney
Two muppets (sorry elmo) in their early twenties in front of me NOT dancing

In front of the muppets is two blokes mid to late forties who are as big as wallaby front rowers...both wore grins from ear to ear and were dancing like their lives depended on it...

Front Rower one accidently bumps girl muppet. Apologises profusely. Boy muppet gets all angry. Front rower one and two apologise.
Muppet boy turns to me expecting a sympathetic ear - Didnt get it -"everyone is here to to dance ,not fight or stand still mate"
Five minutes later
Front Rower two accidently bumps boy muppet. Before front rower has even turned to say anything I see muppet boy loading a punch

- I grab his arm which then propells me between Muppets and front rowers.

This is seen by security plus a stack of people - muppet boy tries throwing a few at the two props - who could eat him for breakfast - but none land as I have ended up standing in between.
Result - security hauls off muppets - thus saving muppets from Wallaby front row
Everyone has a wow of a night dancing - not concerned with Muppets and seeing something incredible
Everytime Front rowers go to the bar (often) they return with a drink for yours truly and thank me from not having their night spoilt

Totally unrelated to windsurfing - but my best save ever.....
