Rumors have been flying all weekend, but it was finally confirmed today that Grey Gardens will end its Broadway run on July 29. The announcement comes on the heels of a press release stating that the 29th would be Tony winner Mary Louise Wilson's final performance in the musical, but now it appears that the show itself will have its final performance that day. The summer has been tough for Broadway, as it often is, but hopefully this will be the last unplanned closing for awhile.
