As noted in Wikipedia:
An award-winning revival of Our Town opened at the Barrow Street Theatre on February 26, 2009. The production was directed by David Cromer, who also performed the role of Stage Manager for much of the show's run. Upon closing, the production had played four preview and 644 regular performances, making it the longest-running production of the play in its history.
Watch this CBS News retrospect, The Lasting Impact of Our Town, that sets the stage for the 75th anniversary of Thornton Wilder's American classic (6:46 minutes).
