WOW!!!! I was there July 28th 1979 and it was hot as h#ll. That was one great concert, although I have to admit after AC/DC I think I was half def! As soon as I saw the post that concert came to mind. There was an opening band that was not on the bill but I can't remember their name, too many mind altering things going on back then and more. There were many other good concerts that I have seen like, AC/DC,Black Sabbath, Alice Cooper, The Who, Judist Priest, Jethro Tull, Kansas, Blue Oyster Cult, DIO, the Firm and many more. The first Concert that I ever saw was Boston in 1978 and tickets were $7.50 each at the Pittsburgh Civic Arena, you can't park your car any more for $7.50. I saw AC/DC w/Bon Scott, open for Ted Nugent. I remember smoking right in the concerts people passing out all over the place, I was at a couple concerts myself that I missed if you know what I mean!! Those were the days!!!
