In the dying days of Napster, I was online with a guy who lived in Alaska in Fall of 1998. He noted that he had tickets to see this show but that it was cancelled at the last minute as announced on the local radio station. Reportedly, however, Chris Squire and Billy Sherwood played some sort of performance locally - but I have no idea where it was held nor why the rest of the band didn't make the show. He didn't know that Billy had joined the band and never gave me any sense of the setlist.
I can only guess that there were equipment difficulties or perhaps another band member had fallen ill.
Sadly I lost contact with the gentleman who had returned to the lower 48 some time later.
