Girl Talk Stage Question

I was just wondering about the Girl Talk show in October. A lot of the fun of the concert is going up on-stage and dancing along with the mass of other people and Girl Talk (Gregg). I didn't know if 9:30 would allow this since there isn't really an easy way to get on-stage I've seen. I've been to his shows where you can dance on stage, but heard at Lolla they wouldn't really allow people on. Just wanted to ask. Thanks!
For safety reasons we do not allow unregulated public access to the stage during shows.
