It's a tough call but I'm gonna go with Chicago on this one. I'd think Annie too but then they'd have to recast again after the summer when Jane goes back to Glee. I have Annie tickets for June 30. Time will tell but I'm going with Mama.
A few months in Annie would get press on the show again, give it a nice bump in sales, and give them time to find another name to cast for a run in the fall (anyone from Wanda Sykes to Rosie to Tyne Daley to Mary Testa).
"I know Jane lynch has never Broadwayed before, but has she Regional Theatre'd before?"
I scanned her book...I remember some early legit stage work and that she got an MFA at Cornell which apparently used to be a big deal acting program but went out of business
