U2 appears and performs twice on the new Tonight Show Starring Jimmy Fallon. The first performance is of "Invisible," which -- like yesterday's rehearsal -- is recorded on the Top of the Rock observation on the 70th floor of NBC's "30 Rock" headquarters. The band does two takes of "Invisible" on the rooftop, with accompaniment both times from members of the Rutgers University Marching Band. They also do a short interview in the TV studio and perform an acoustic version of "Ordinary Love" that starts out with just Bono and The Edge performing. Larry and Adam join in later (playing tambourine and acoustic bass, respectively) and Fallon's house band, The Roots, eventually joins in, too.
