Brian,
I got to see Gordon at Meadowbrook in July of '06. I grew up in Kalamazoo, and my husband, my mother, and I were visiting my brother and sister-in-law who lived in Rochester Hills at the time.
He opened the second set with Sit Down Young Stranger, the only time I have ever heard it live. The crowd roared at the "war is not the answer...young men should not die" line.
We had very similar weather, and the same encore
Even worse than the rain, though, was my brother's wife calling the show, which was excellent, the most boring show she had ever seen. And she kept saying it.
