Wow. Krokus was one of my favorites too. That neighbor also introduced me to them, and I was a big fan for years. I saw Krokus, W.A.S.P., and Helix at Sacramento Memorial Auditorium around 1986 or so.
I saw everyone in the 80’s. This weekend I am going to blast Metal Gods live at the US Festival 1983. Judas I just love them. My last concert was the Scorpions in 2003 I was pregnant lol Whitesnake was the opening act.
