Call Of The West Wall of Voodoo/Los Lobos. We were 16 and big fans of Wall of Voodoo's first two albums - "Mexican Radio" was a big hit at the time - so we drove about an hour up to the Pantages Theatre in Hollywood; my buddy was later busted for telling his parents there was a local birthday party. After a couple of nips of Bacardi on the way in, we settled in for the opening act, Los Lobos - pre-How Will The Wolf Survive, the local hipsters weren't very kind to them ("get off the stage, Grandpa.") - bad scene.
Wall of Voodoo delivered the goods - Stan twitching around even more than in the 2006 redux clip attached, the guitarist Marc Moreland bending up and down rhythmically, a generous setting on the smoke machine creating a theatrical line between the band and audience while Stan snarked out "son, this ain't no movie matinee/you're a long way off from yippee-yi-yay." The crowd surged, and The Pantages, normally a playhouse back then, did not respond well - the same friend who lied to his parents was, after a brief warning, hustled out the back door and into the alley for dancing.
Great show, great band(s), great start to a concert going career.
