Well Les, they were all on nasty lookin' canned beers - musta bin the lead solder a la Franklin expedition!
Personally - I spied the predicament in good time (as George pointed out up above) and sent a courier round to the Morrisons next door.
Cheap bottled beer! My word, some of it over 7% - Eek!
Don't think the Arts Centre Officials would've approved!
Had to hide it!
But mostly they got high on singing mightily all night. Rah!

OK - I'm a bit unoccupied at work and rambling a bit just now... but what the hey...
I thought I might explain the 'glasses' quip from George too (though you may have been one of those there Les, others reading this thread won't have known what El G was referring to....
At Gainsboro Fest in Oct I was (blush) asked to sign a few CDs after a concert.
The first chap in the queue lent me his specs as I couldn't see a thing close up and mine were packed away.
Collecting his signed CD he turned and left me on with the next...and on...
Over half an hour later (after I'd helped the organisers move all the chairs down a flight of stairs!!)
Fest 'main-person' (Sue) turned and said 'Oh, you've got new glasses on'.
I pulled 'em off to look at 'em and realised what at happened.
At that PRECISE moment, through the window in front of me I could see this red-faced figure powering purposefully up the path towards the door...
Poor chap had just come hot-foot back from his hotel to try and rescue them! The timing was spot on!
The small crowd of helpers around not only laughed themselves silly at me, but haven't given up extracting the Mickey since.
Hic! HFA - Duncan
