Judging by the remains of the sticker on the back, I got this at a Music Plus. That chain ended up merging with Blockbuster and then going out of business.
The Avengers play Los Angeles and Duke Dunton was there. The opening band later had more success when they got slick and produced. At this point they were punk and could hardly play. The only thing I remember about The Flyboys was that they did a Monkees cover.
