I've met the guys (well some) before & after some shows at their hotel. I live at a city where it's easy to predict where they'll stay, the promoter always books the same place.
First time was for BCSL tour, got pictures with MP, had 3/5 autographs on the red cover version of lifting shadows. Pirate was feeling bad so no shot there, and JM was REALLY pissed since on the way from the airport some stupid teenage fans started "racing" chasing after their van and they almost crashed. So yeah, no shot there. JP was even more pissed than JM and I ended up thinking he was a jerk.
Quite the opposite!!!
Last year we (gf&me) caught him & MM after the G3 show (same hotel, plus talked with satch and LaRue&Morse, it was awesome) and JP was on cloud nine. He probably talked to the 6 or 8 fans that were at the hotel for about 30 minutes about everything, asked about our favorite stuff from ADTOE, signed stuff and took pictures. It was most amazing to see how happy he was. MM is a rather humble (and short!) guy, he apologized for not being able to shake hands ( he had injured his wrist and was barely able to play ) but came down, spoke for a while and took more pictures.
I have to say it's one of my most precious memories. I don't know how the M&G ambiance is, but if you ever learn where they're staying, definitely go there after the show, while they're still on the post-coitusshow hype.
