Unidentified outdoor concert, summer 1976

[Sanne2]

I found a whole set of pictures from an undated concert. All I know (based on Stevie's green hair), is that it was sometime between June and August 1976, but according to FMLegacy they played a whole lot of outdoor shows at stadiums that summer. I like to tag my pictures with the correct date & venue as much as possible so I'm hoping that somebody recognizes the stadium or the concert based on these pictures? There's a sign visible behind Lindsey with a logo, but I can't make out anything but ".......Stad"
