He just passed through my area in the last month or so at a small folkie venue. I really wanted to see him (never have) but family commitments said otherwise. Now I really regret missing it. The same thing happened to me again last night-Kris Kristofferson did a solo show nearby which I missed and this morning's paper had a pretty glowing review of it-he did 30 songs, spanning his entire career.
Thanks for the heads up, I will definately catch Keller Willaims the next time around, especially if it's the Incident variety.
