The band that opened for War wow'd the crowd... standing ovation. Anticipation was high when War took the stage. Unfortunately - the lead guitar player for War was blind drunk. Seriously. He could not play.... wrong note after wrong note as he barely kept his balance thru a couple of tunes - at which time he was escorted from the stage.
War continued but while only the lead guitar player was incapacitated the other members were close. A chant rose from the crowd to bring back the opening band. The chant grew into a near riot and War cut short their performance.
By the way... the opening band? ZZ Top... they were unknown at that time... at least here. Not long after ZZ Top returned in concert - - - as the headliner... they were an instant smash hit.
