The only one I can think of off the top of my head is Avenue Q.
"You will understand that Bww is a forum that allows Theatre people, Fussy old Queens, and chorus boys of Mama Mia to release their everyday life's frustration by being Snarky, B**chy, and sarcastic."

A Catered Affair and Cry-Baby do not have Monday night shows anymore, that was during previews. Chicago, Rent, Avenue Q, and Phantom have Monday evening performances.
There are always cool benefits with theatre stars on Monday nights that are always a better bet than going to see Chicago again. I often find that there are too many tempting options on a single night, although considering it's Tony season and the beginning of the summer there's a bit less going on than usual.
