I voted 10 stars mostly because, well, I'm in this movie - sort of - my hand is definitely in it.
This was a concert that occurred on a Friday night, 17 October 1980 in the Nassau Veteran's Memorial Colisseum in Uniondale NY on Long Island.
I was at this concert in the 2nd row on the floor in front of the stage. I remember being right in front of Geezer Butler of Black Sabbath. (Sabbath opened that night, with Blue Oyster Cult being the second band. The next night,Saturday, the concert was held at Madison Square Garden. BOC went first and Sabbath went second for that show. I was there too but far from the stage.)
Anyway, back to the movie. This movie was actually an episode of Don Kirschner's Rock Concert which, if I remember correctly, was on NBC (in the New York market) appearing after Saturday Night Live.
The movie itself probably had more footage than the episode of DKRC.
Anyway, the Black and Blue tour was a big tour in 1980, so it is easy to see that they would take all of that footage for DKRC and would turn it into a movie. This was the era when teenagers often would smoke dope at the midnight movies such as "The Rocky Horror Picture Show" or "The Grateful Dead" movie. So, the Black and Blue movie would fit right in... And, yes, I saw it at The Uniondale Mini Cinema in Uniondale NY which was famous for starting the Rocky Horror craze.
So, keep in mind that this movie was most likely filmed on videotape and was originally destined to be seen only on television.
If you lived "That 70s Show" and especially liked those bands, this would be a good movie for you. Other than that, it's a good historical piece for illustrating the rock and roll concert-going life and the end of the 70s / beginning of the 80s. While it's not Woodstock, it definitely illustrates how times had changed in the 11 years between Woodstock and Black and Blue.
