I would be willing to bet that tickets for Follies would probably be gone by 1:00 if you go on the weekend, but if it's during the week, they might still have them. Also, I don't know if you've seen On a Clear Day yet, but you could probably get that rush around 1 on any day and it's worth $30, I think.
