One of my favorite shows

I saw many really, really good concerts in San Antonio at the Municipal Auditorium. One that tops the list was a three band show consisting of Trapeze, Blue Oyster Cult and Foghat(?). Not sure about Foghat because they seemed to be on just about every other show there in the late 70's. Anyway, Trapeze closed the show and they were playing songs from Hotwire so it was the Galley, Wright, Kendrick and Holland line-up. I remember that as having a profound musical impact on me as I had never heard rock played in that fashion (funk). I also remember BOC having a better crowd response which I attributed to the fact that they were touring in support of On Your Feet Or On Your Knees album which was doing really well. It seems as though the new style of music that Trapeze was playing caught that San Antonio audience a little off-guard and perhaps a bit biased. Would love to hear from anyone that was at that show (and can remember it, always lots of substance abuse at the shows back then).

I also remember that show as the first time I saw a particular lighting technic used "gobos". That effect was reserved for Trapeze so apparently they had their own lighting designer who actually knew what he was doing.
