David,
Thanks for the good report; after I last saw them here in central NJ 2 or 3 years ago, I was very concerned for the group. On this particular night, Gillan was constantly running backstage, after nearly every verse (not song, but verse), and I was quite worried for the man. We were not sure if it was medical related, or simply too much whiskey before the show. I just remember being very uncomfortable during the performance, and have not considered attending a show since. Perhaps it was 'just one of those nights', glad to hear things are good again.....
Chris
