Molly Hatchett, April Wine, Rush, Triumph, Scorpions, BOC.
Rocklahoma with Pat Benatar, Sammy Hagar, Van Halen, and the Doobie Brothers (unfortunately, with Michael McDonald).
Triumph put on the best show of those that I saw. Ric Emmett was able to mix up some hard rock with some quiet acoustic stuff--made for a great show. Best pyrotechics as well.
My regrets: I didn't see Jethro Tull at their height (Songs from the Wood tour would have been cool); but much worse, I never saw Stevie Ray Vaughan play.
Cheers.
