Over the years I've been to around 5 of these evenings. If you want to get a 'good' view it's best to get in early and stand in the front row, since it's blink and you'll miss it.
I remember the first one I went to back in 2004, there was a player who was a solid lad, yet the proportions God blessed him with didn't really equal out (if you get the drift) and once his gear came off, he just stood there proud as punch and was the player who remained naked the longest (it was still only brief nudity). It was a hoot.
I wish the Sydney Rangers soccer or Sydney Stingers water polo guys had an evening like this, they're way cuter than the Convict players are IMO.
