Harold Mabern: The audience was great, and I would say you probably had 98% African American people in the place that night. Audience participation was great; during that time all audiences were great, but there were a lot more black people involved because what we played they could relate to. When that free stuff came in we drove the people away; like  Lou Donaldson said, you gotta play the blues for the people. Anything you play can be bluesy if you’re doing it within the right context.
