From what I've discovered so far, Club Matinee was THE place for blues in the south. I've found mentions of him in biographies for Cab Calloway, James Brown, Ray Charles, pretty much everyone that was any one. Texas Room had very little on him except mentions in social pages. The African studies library had two lines in their file on the club, they actually copied MY notes to add to theirs. The Blues museum is being built right where the club stood, but it's not open yet. Talked to some gentlemen around the area and they gave me a bit of history on the place. One of them found a friend that worked for Dickerson back in the 60's and 70's. If what the man said was true, he was quite the powerhouse in local politics. Dickerson, along with a gentleman named David Robey controlled the Fifth ward for decades. Dickerson owned the Crystal White cab company (this is confirmed), the El Dorado night club, and half the businesses. Robey ran Peacock records rather ruthlessly according to sources. One source even mentioned how he laundered his money from the casinos, but I have no way of verifying that.
