The band played for over an hour and 30 minutes playing hits from the "Evolution" and "Infinity" as well as a few songs from the albums before Steve Perry joined the band.
Steve's voice is a very nice addition to those which really make them come alive. I've always thought the balance between Steve Perry's and Gregg Rolie's voice is part of what made the band so special.
Here is a copy of the review that was in The Tulsa Tribune the next day, Saturday July 14, 1979.
It's a great review about the band, the show and the massive stardom they are about to embark upon.
