they may have a rush, but if they do it'll be very limited. for the last two performances on sunday, they only have a few scattered seats left. good luck though!
color purple, always puts aside the first two rows for rush. you arent able to purchase those tickets, until the box office opens day of performance. if you are rushing this sunday, i imagine it to be a bit crazy. maybe get there before 6 if possible, however for the matinee it might be different since most people are trying to get into the evening show.
