Wyn,
If I'm not mistaken you've asked this question before, eh ? Anyway try emailing his management team at EMP and ask to be put on the list. That way you can go to the "meet and greet" after the show is over.
Your other alternative is, depending on the layout of the venue, to wait outside the stage door or inside near the stage. Many venues will ask you to split if you try to wait inside, but some are set up for it.
If you wait out by the stage door you will need to plan 45 minutes to an hour. (during that time he will be "meeting and greeting" those people who are on the "list"). Once he comes out he's real friendly but depending on where they're going next his time spent with the alley dwellers often is fairly short - but nice.
I'd try the email or phone call route first.
Have fun,
Bill
You can also try calling the venue, they sometimes have their own meet and greet list.
