Thanks to everyone who contributed their memories about the opening of the "A Private Heaven" tour. I posted this because it was to the day (a Thursday evening) and I remember one other fan, several years ago, posting a set list from that first night.
As for the reference to "90 minutes under the gun". I heard a radio special in April 1984, In which she explained the lyrical significance to this phrase. Also the previous line "Flying East to the Rising Sun". Obviously refers to her Asian tour at the time. It was a quirky interview Sheena gave. I can't recall the title or who the interviewer was, but the program was at least an hour long. Maybe one of our fellow fans can recall this interview/research it/or has is recorded somewhere?
I also have my ticket stub and some newspaper clippings from that concert. I'll have to upload them soon.
