''Hedwig,' 'Mamma Mia!,' 'On the Town' All Closing in September

With the turn of the calendar to a new month, it means new shows will be debuting on Broadway. Of course, it also means the closing of a few more. As the start of September rolls around, the Broadway community will witness the final bows of three big Broadway productions: 'Hedwig and the Angry Inch,' 'Mamma Mia!,' and 'On the Town.' All three have been struggling to sell tickets for some time now. And as they do say, all good things come to an end.
