Fall Out Boy had quite a bit going on yesterday. First off, they stopped by the Late Show with David Letterman to perform “I Don’t Care” off their new album, “Folie A Deux”. Then they had a concert special on Fuse of their show at the Chicago Theater at 9pm EST. Then they played a sold out show at the Nokia Theatre in Times Square NY (Videos to come later). Check out their performance of “I Don’t Care” on Letterman below.
