Rush Concert - Chicken?

Hubby and I went to see Rush when they were in Austin last week. We both like Rush and listened to them when we were younger (back in the "Tom Sawyer" and "New World Man" days), but neither of us were dyed-in-the-wool, play-the-cassette-over-and-over-again-on-auto-reverse kind of fans. So, we are obviously not privy to some sort of private chicken joke. During the (awesome!) concert, there were three GINORMOUS commercial rotisserie ovens full of chicken, cooking away. Some dude in a chef's hat and apron would periodically come onstage and baste them. It was weird. And hilarious. I will say that the females were completely outnumbered by males in attendance - an interesting change from the Hannah Montana concert we attended recently, where there were so many females that some of the mens' rooms were temporarily converted to womens' rooms. And I have a bit of a crush on Neil Peart now, after his AMAZING PHENOMENAL THERE AREN'T ENOUGH SUPERLATIVES IN THE WORLD drum solo. If any of you know what the deal is with the chicken, please let me know.
