Yes' only IOWA concert (I think!) -- the Four Season's center in Cedar Rapids is a less than ideal cement hall, but Yes filled it with a mighty sound. I do remember (after reading the JA snippet from Seconds Magazine) that they played Circus of Heaven and Jon told the crowd it was special because it was his Son's voice......
They definately played Awaken, On The Silent Wings of Freedom, and Don't Kill The Whale. No CTTE. I recall the setlist being very similar to the 4/18, 1979 show -- the medley was there, including "Long Distance Runaround", but I do not recall and "Fish" unless it was a greatly shortened version..........
I was just moving to Iowa in the next month or so and was visiting and happened to catch the show. I bought tickets the day of and got fairly good seats, although a bit high to one side. There really were few bad seats in the house. My last Yes concert (I'm so excited by the OYE show coming up.....)and I did sense at the time it was the close of an important chapter. These shows were no less musically magical though the music was still angelic and incredible.
