Hi Charlene, Yes, an ancient history lesson!
I wonder why you were asking about Red Rocks; any indication that Gordon might be scheduling something there? That would be worth the trip for multiple reasons. My friend and I graduated from college in June of 1969 and gave ourselves a trip across the USA on a meager budget as a graduation present. Several of our stops intentionally coincided with that PP&M tour, but we didn't have the funds to make the Red Rocks stop although we wanted to. When Gordon played the Denver Botanical Gardens in 2009 or so, I finally visited Red Rocks just to see the location, and as Sir John has pictured it, it is truly breathtaking, and I hear the sound is awesome as well. I can't quite remember if Gordon had any accompaniment that summer; my best guess would be that it was just he and his twelve string guitar. At first we were horrified to see Gordon night after night taking time away from PP&M's usual 2 1/2 hour performance. It had always been their custom to appear with no opening act. The concept of Albert Grossman, PP&M's and Gordon's mutual manager, was to introduce PP&M's audience to the virtually unknown in the States Gordon, thinking that they would be the same audience. He was right. It wasn't long before we were mesmerized by the man, the music, the brilliance and intensity of the compositions, Grossman's plan was working, new fans being born nightly, faithful fans as the subsequent decades have proved. So it's 44 years and counting. And hoping for many more.
