When I met most of the guys (i say most because Portnoy was already at the venue), I was just in the hotel lobby asking the receptionist a few questions. I turned round and JP was stood behind me, we chatted and did the whole autograph/picture thing, then JMX came out of the elevator, i turned round a lo and behold James is stood there and he says hello and finally behind James sat on the couch was Jordan. I just chatted with the guys and got autographs/pics and they also got a promo pic and signed it during the intermission of the show, so I could get Mike's autograph, which they left at the Box Office for me to collect.
All in all an awesome experience, I still hope to meet MP one day.
Just remember if you do bump into them, stay cool and they are all awesome guys to chat with.
