Hi,
I have 2 good seats for The National at BAM on Sat Feb 23. They are in the Mezzanine, seats F 5 and 7. (I saw Sufjan from around there-good view)

I am looking to trade them for 2 seats on Fri Feb 22. Turns out my best friend's bday party is that Sat and I am in big trouble if I miss it.
Please help!
