After graduating in 1963, Simon joined Garfunkel, who was still at Columbia University, to perform again as a duo, this time with a shared interest in folk music. Simon enrolled part-time in Brooklyn Law School. By late 1963, billing themselves as Kane & Garr, they performed at Gerde's Folk City, a Greenwich club that hosted Monday night open mic performances. They performed three new songs—"Sparrow", "He Was My Brother", and "The Sound of Silence"—and attracted the attention of Columbia Records staffer Tom Wilson, a prominent A&R man and producer (who would later become a key architect of Bob Dylan's transition from folk to rock). As a "star producer" for the label, he wanted to record "He Was My Brother" with a new British act, the Pilgrims. Simon convinced Wilson to let him and Garfunkel audition in the studio, where they performed "The Sound of Silence". At Wilson's urging, Columbia signed them.
