||Mint Tattoo and local Corvallis band Big City Blue were the opening acts. Although the poster says "OSU Colliseum", the venue is actually called Gill Colliseum. Although scheduled to, Mint Tattoo may not have actually played. Marshall Adams, guitar player for Big City Blue had this to say: "Big City Blue came together for the Grateful Dead Concert at OSU Gill Coliseum in Fall Term 1968. We were to open and Mint Tattoo was to also be featured. We had one set of material with Jimmy Hibbs doing most of the vocals and rhythm guitar, Jim Knight on Bass, Ron Leach on drums, and Marshall Adams on lead guitar and folk flute. Well we opened and it went quite well.........35 minutes later we went back on and did our set again. Seems that Mint Tattoo was busy out in the parking lot doing whatever bands would do in a parking lot."
