Ha ha... always tricky this...should I, or shouldnt I... I covered this in another thread on the forum, but happy to do so again.
If the crowd seems "appreciative" of any antics that I've already done that evening...then something unusual takes place after the queue has disappeared from the buffet table.
The background music fades, all the Roadshow lights dim...except the red ones which pulse on and off....A red alert klaxon sounds (off of the Star Trek sound effects CD)...and the James Bond theme music starts.
I pop up from behind the decks, wearing green balaclaver helmet (and still in bow tie, dinner jacket etc)...and I steathly tip-toe/wall hug my way to the buffet table using all available natural cover...Pillars, Pushchairs, people, balloon sculptures etc etc... make it to the buffet table....look around for Odd Job/Jaws etc... grab a plate...chuck about 5 random items on it and dash (crouched) back behind the Disco, where I hit "start" on the Milk Tray music....and say into the Mic... "And all because your DJ loves, Prawn Vol-au-vants, Egg sandwiches, Vegatable samosa, chicken nuggets....etc...etc...etc... to fade...
I keep toying with the idea of adding a few sound effects of gun shots, or a quick (invisible) fist fight etc...but havent got around to it yet...
As pointed out by someone here, last time I posted this, the use of the balaclavier helmet is not recommended in Northern Ireland.

just in case... and I guess the same advice applies to Army base gigs.
