August 18, 1979 Cal-Expo Blue Oyster Cult, Cheap Trick, Pat Travers Band, and Shakin' Street.
The first of many times to see BOC and Pat Travers (still one of my favorites today).
I'm completely jealous. The one band that I never got to see that I wish like hell I could turn the clock back for.
Seen the Who, the Stones, Metallica (several times), Van Halen, Van Hagar...but never Zepp.
