Sidney Fields in this movie?

A source on the internet says that Sidney Fields appeared in a bit role in this movie. Sidney Fields was a vaudeville comedian who is most famous for his role as the landlord (and other roles) in the Abbott&Costello TV show. Does anyone know if this is true, and if so, where in the movie he appears? I bought this movie for this specific purpose, but didn't see Fields in the movie.
