My favorite Freebird incident was when I saw Opeth. Someone yelled it out, and Mikael stopped and said, "What? What's 'Freebird'?" Got some laughs from the crowd, and he said, "No, seriously, what's 'Freebird'?" It got a little uncomfortably quiet, and the guy who yelled it started explaining, and after about 10 seconds, Mikael said, "Dude, I know what 'Freebird' is. We're Swedish, not stupid. But wouldn't you just sh!t yourself if we played it now?"
