You forgot the 1981 Oct 18th Blackfoot & Def Leppard at the Pershing Auditorium in Lincoln, Ne. Def Leppard opened up for Blackfoot and Def Leppard was not even a know band name and wasn't even on the venue or ticket stub.

Oct 18th, 1981 at the Pershing Auditorium in Lincoln, Nebraska. This was before Def Leppard was even well known not even known at all in the U.S. They opened up for Blackfoot in Lincoln, Nebraska, at the Pershing Auditorium. Def Leppard was not on the ticket venue nor even listed or announced until the show was about to start. We had partied with Def Leppard the night before the concert filling the bathtub in the hotel with 10 cases of different kinds of beer & ice. Partied all night until about 6:00am the day of the concert. I will admit telling my friend Jim Bogensberger, Allan Douglas & Mark Brodkey that after Joe Elliott told us the name of his band was Def Leppard. That was the dumbest Name for a band that I've ever heard, and that they were going nowhere fast. I was wrong. A few months later they hit the top of the charts. And with egg on my face, my friend Jim said, "look who's #1 on the music chart", Yes, it was the infamous Def Leppard !! By David Salonis, and that's the story, well at least part of the story.
