Broadway, The American Musical

I have spent the last several Sunday evenings watching some of the PBS offerings: Broadway: The American Musical http://www.pbs.org/wnet/broadway/.  These are wonderful offerings, and vary in content. It might talk about the Depression, racism, patriotism, the early offerings, the 1920's, the 1930's, 1040's and 1950's.  These are wonderful explorations of the theater in America.  Good stuff.
