The best was 1977...on their first trip to the States, Judas Priest opened a "Day on the Green" show for Led Zeppelin.
I was at a Judas Priest "Unleashed In The East" concert in Japan which they made an album of, as well as the US Festival in 1983 (put on by Steve Wozniak of Apple) - Heavy Metal Day featuring Quiet Riot, Motley Crue, Ozzy Osbourne, Judas Priest, Triumph, Scorpions, and Van Halen.
I saw them other times as well, I just can't remember the details...(hehe).
BTW, I was also at one of the Scorpions "Tokyo Tapes" concerts. Supposedly the ticket stubs are worth quite a bit now.
Ah, the memories...
