Not sure if all these shows have a Saturday evening performance, but:
The Light in the Piazza (beautiful, your sister will probably be bored to death though)
Hairspray (perfect...your whole family would love it)
Mamma Mia! (fun, cheesy, badly put together but totally entertaining)
Movin' Out (haven't seen it but I know it's closing in December and hear only very positive things about it)
The Color Purple (it should be open by then and everyone I know that saw it in tryouts etc said it was great)
Doubt (an incredible show that must be seen to be believed...your sister may be bored at this at well and may not understand the plot *it regards child molestation*--check my blog for a review if you want)
Sweeney Todd (the production is a little flimsy, but the material is just so amazing as are the performances that this production is a must see...your sister may not like this one either, its intense)
Chitty Chitty Bang Bang (again, havent seen it but hear its adorable, the performances are all great, and its very fun no matter how dumb and corny it may be at times)
RENT (what with the movie coming out soon, this will be a tough show to get a ticket to, probably...it's great, and your sister may not fully grasp some of the baffling story lines and issues, but the music is just amazing)
Chicago (sexy, sultry, fun, exciting, simple, and an all around fantastic production...it's a great, great revival)
Again, there are reviews for a couple of these on my blog if you want to check. =)
