Panic! At The Disco have just released their latest album Vices And Virtues literally last week and have been all over the place promoting the hell out of the album. The band which now consists of just Brendon Urie and Spencer Smith have gone back to the bands roots and the new album is a little more A Fever You Can't Sweat Out as oppose to Pretty Odd. In turn, last night they paid a visit to Conan O'Brien and his late night slot to perform the incredibly cathchy "The Ballad Of Mona Lisa" which has a way of becoming stuck in your head. Ask Rocko and he'll be the first to tell you this song reverbarates around your head for days after you've heard it, seriously.
