As long as we've creeped this into talking about Rev. Gary Davis:

I think it was in the 1970s, but maybe the late '60s, that the Chicago folk club called Mother Blues (owned by Lorraine Blues -- 1305 N. Wells St. in Old Town) brought in Gary Davis for a week long gig. Gary either got drunk or just lost himself on stage, but after being warned a few times, the Rev kept on doing instrumentals, like a military march he usually did great. Those lasted a half hour or more each, and destroyed the club's attempts to be on a schedule of some kind. Gary was "fired" -- and sheepishly went home to New York. His wife could always control him, so he was told to come back with her if he wanted to do the job right. He DID bring her back to Chicago with him -- and everything went fine after that.
