Missing cast
Why does the cast listing on IMDB exclude all the principles for this show? No Amos, no Andy, no Kingfish, etc. Seems like a listing of guests or secondary characters.
and yes, this was a great show that I don't remember thinking anything about the "color" of the characters. I remember Kingfish trying to send Andy on a cruise boat that was really like a tramp steamer or something, and when Andy asked what the shovels were for (stoking coal), Kingfish told him they were for that all-American game, Shovelboard! I still crack up over that line.
It's all in the reflexes!
