I can answer that one: once the stooges hit in Boston, I do believe they released almost every comedy short in the Columbia vaults. It was my first exposure to Buster Keaton, Harry Langdon, The Shemp solo shorts, El Brendel, Andy Clyde, and I even remember The Glove Slingers. I was maybe six at the time. They ran them before school and after school. The non-stooge shorts didn't last very long, the Stooges just smoked everybody. I remember the Glove Slingers being downright pathetic, every short ending with a juvenile boxing match, egged on by the grown-ups who today would be booked for child abuse. The kids just soaked the good comedies up, nobody more than me. Oddly, if they ran any Charley Chases, I don't remember them.
