most-produced plays

TCG has compiled its annual list of most-produced plays at professional theaters in the U.S. (excluding Shakespeare and A Christmas Carol). Here they are for 2008-09:

Doubt by John Patrick Shanley (14 productions nationally)
The Santaland Diaries adapted by Joe Mantello from David Sedaris (14)
Rabbit Hole by David Lindsay-Abaire (13)
The Seafarer by Conor McPherson (12)
Eurydice by Sarah Ruhl (11)
To Kill a Mockingbird adapted by Christopher Sergel from Harper Lee (10)
The Glass Menagerie by Tennessee Williams (9)
Souvenir by Stephen Temperley (9)
Mauritius by Theresa Rebeck (9)
Noises Off by Michael Frayn (8)
Radio Golf by August Wilson (8)

Comments:
Doubt is coming up at Interplayers. Rabbit Hole, Souvenir and Noises Off all done in the last 2-3 years at Actors Rep (now defunct) and at the Civic. How long ago was Glass Menagerie done at the Civic? About nine years ago, but I'd have to check.
I saw Eurydice in Portland. The NEA's Big Read, in its Spokane manifestation, will concentrate on To Kill a Mockingbird in February. Not too bad a record; we probably wouldn't want to hit ALL the most popular productions, anyway: It's good to innovate with new programs.
This 2008-09 list of TCG productions was published a year ago, as a preview; the 2009-10 preview will be out in next month's American Theatre magazine.
For further analysis, and a pic of an L.A. production (at the Ahmanson) of Shanley's Doubt, go here.
