I was there last week, and for Dug and Russel, I think we may have waited about 20 minutes. Part of that wait was so Dug and Russel could take a break. I don't know about Pocahontas, we didn't see her.
I got in the line just as it was being cut off for her set, I waited about 20 min. This was the day of the EE 5K a few weekends ago, no idea what the crowd level was that day.
