For me a lot has happened and changed since this tour, so I could be wrong but I doubt it. I am sure that the tour was supposed to open in Des Moines Iowa. When it was announced they would be playing Veterans Memorial Auditorium I was there hours before tickets went on sale. I was able to purchase front row seats and was thrilled at the thought of seeing them again after over ten years. To my big disappointment, they cancelled this date due to poor ticket sales! I guess Des Moines got what they desrved at that time.
Actually, Robbie Eagle was the offstage keyboardist. And he only played on "Hold On". I don't blame Kaye. You can't play three lines at once. And the "Changes" intro is beautiful. And that is Kaye playing.
The August 1991 KEYBOARD talks with Kaye's keyboard technician, Robby Eagle, who says he did some keyboard work under the stage for both the BIG GENERATOR and UNION tours, but he characterized it as very limited--probably true, because he wouldn't have been so excited about how much he got to contribute to "Hold On" if he were contributing much to all the other songs as well.
