前年リリースのソロ第2作『Principle of Moments』を携えたワールドツアーの一環で、ソロとして初の来日公演。
His first solo tour of Japan (Festival Hall) in 1984.
There are no seat number stamps (they were rubber stamped at the time), so this is likely a sample or for someone involved.
This was his first solo performance in Japan as part of a world tour promoting his second solo album, "Principle of Moments," released the previous year.
