I order up a lot of tapes from the archives of different versions of the same famous play.  The reason for this is to show how different each interpretation of the same script can be.  In one of the versions the stage is covered with hundreds of red stilettos, in another version there is a bath with black and white squares printed on the bottom for playing chess.  The archivist is so excited that someone is interested in these versions and that they might see the light of day.  I tell him I did the same experiment with Porgy and Bess last year.  One of the versions was with dogs and Frank made his entrance on a skateboard.
