Why were my comments deleted? I wanted to know if Jackson Browne actually played at this show. I was at the concert and i don't remember him. Thank you?

I remember this wonderful concert very well. I was working as a local roady for the Lippmann+Rau concert agency in Frankfurt at the time, a schoolboy job that I loved! I remember we had a problem with Joni's grand piano, the lacquered surface reflected the light of the spotlights onto a row of seats in such a way that those sitting there would not have seen anything due to the glare. So we turned the piano a little bit, Joni was asked if that was ok, (it was), and all went well.
