I believe I was at that concert in Pittsburgh. The concert I remember Yes opened for Edgar Winter's White Trash. I don't have the stub to confirm the date, but the timeframe is right.
I remember it being one of the finest shows I had seen up to that time. Yes opened and blew the crowd away. Then Edgar came out and tried to top and might have done so, depending on who you ask.
First of several Yes shows I have seen over the years.
