Thin Lizzy cancelled. I know because I had bought tickets mostly to see them. Didn't know the backstory of Gary Moore walking out. As I recall there was a bit of a beef about possble refunds as Journey were the "headliners", but I went ahead and went to the show. They were the best version of Journey, with Greg Rolle still in the band.

The program you have pictured was for the entire summer series and there were some great shows. It was printed well before the summer and had all the acts listed, so Thin Lizzy appears in it. I went to five of the shows that summer (Talking Heads/B-52s, Ramones, Tubes, can't remember the other one) but I never got to see Phil before he passed.

Thanks for the great site
