Moran & Mack--Two Black Crows

While this wasn't a radio show per se, it is safe to assume that Moran & Mack's "Two Black Crows" comedy/novelty records received at least some airplay in their day. Recorded and released by Columbia Records between 1927 and 1929, these recordings of the vaudeville team of George Moran and Charles Mack are a thematic forerunner of Amos 'n' Andy. The latter are much better known today because they concentrated their energies on radio, while Moran & Mack were primarily a stage and recording act.
