[Beat Surrender]

I listened to the video posted of "Interracial Chemistry" improv - did he call it that, or where did the title come from? Was there an intro where he explained it? Just really curious. It felt almost like it could also be about what's happening in Indiana with "religious freedom" which is why I was wondering if he actually says something in the song about race at all? Maybe I just couldn't make out the lyric.
