The "Mamma Mia" overall count is now at thirteen, at eleven different venues: the Shubert Theatre (formerly in Los Angeles), The Ahmanson (in Los Angeles), Mandalay Bay (in Las Vegas), the Pantages Theatre (in Los Angeles), Orange County Performing Arts Center, the Pasadena Playhouse, the Long Beach Civic Auditorium, the Cadillac Winter Garden (in New York), Orange County Performing Arts Center again, the San Diego Civic Theatre, Mandalay Bay (in Las Vegas) again, the Fred Kavli Theatre at the Civic Arts Plaza in Thousand Oaks, and the McCallum Theatre in Palm Desert.
The show is also currently playing at the Pantages again, but because we weren't terribly enamoured of the company that we saw at the McCallum, who would be the same company playing the Pantages, we decided not to go. How weird is that? But we have seen the same company before multiple times, so that in itself wasn't an issue. We wouldn't have even had the added benefit of a new venue to add to our list since we've already seen the show at the Pantages.
And even weirder than that is that while we're not seeing the show even though it's playing locally, I know five different people who did see the show during its current run at the Pantages.
I think we've actually run out of local venues now.
