Paul Simon and Art Garfunkel joined forces for a surprise reunion last night (Feb. 13) at New York’s Beacon Theatre, which was hosting its first event after a seven-month renovation by Madison Square Garden Entertainment.

The pair performed “The Sound of Silence,” “The Boxer” and “Old Friends” during the encore, marking what is believed to be just their third appearance together since concluding a 2004 reunion tour. Garfunkel had flown in from Florida, where he played in Key Largo the night before and was scheduled to play in Fort Pierce tonight.

The reunion added extra glitz to an evening attended by celebrities such as New York mayor Michael Bloomberg, Paul McCartney, Jon Bon Jovi and Jimmy Fallon, and showcased the Beacon’s refurbished interior and new sound system.

Simon played an eclectic two-set show, drawing equally from classics such as “Me and Julio Down by the Schoolyard,” “Slip Slidin’ Away” and “Graceland” as he did songs from his ill-fated Broadway musical “The Capeman” and newer material such as “Father and Daughter” and “Amulet,” a collaboration with Brazilian vocalist Luciana Souza.

Also featured were off-the-beaten-path cuts such as “Duncan,” which hearkened back to Simon’s folk roots, “Train in the Distance,” from the critically maligned 1983 album “Hearts & Bones,” and “Loves Me Like a Rock,” a 1973 precursor to Simon’s future dabbling in African music.
