For me, for this tour, the only way to get an autograph was with a VIP ticket. With those, we had the chance to give something to the VIP helper (Zach), and he carried it backstage to Peter. We didn't have a chance to talk to Peter in person.
It doesn't seem there are VIP packages so far for these new dates.
I will say I'm not disappointed about not meeting him. I'd have been totally flummoxed as to what to say, anyway. And I am SO THRILLED with my autograph!

So get one if yoiu can! It's on a rather rare album sleeve - German + Japanese. I should take a photo!
