Panic! At The Disco stopped by Conan to perform the first single, "The Ballad of Mona Lisa", from their latest record, Vices & Virtues.
It is the band's first performance on Conan with their new line-up, as they begin to promote the record with a string of night talk shows. Lopez Tonight is next on their schedule, with their appearance expected to take place on April 4th, 2011.
