Under Big Records, Simon and Garfunkel assumed the name Tom & Jerry; Garfunkel named himself Tom Graph, a reference to his interest in mathematics, and Simon Jerry Landis, after the surname of a girl he had dated. Their first single, "Hey Schoolgirl", was released with the B-side "Dancin' Wild" in 1957. Prosen, using the payola system, bribed DJ Alan Freed $200 to play the single on his radio show, where it became a nightly staple. "Hey Schoolgirl" attracted regular rotation on nationwide AM pop stations, leading it to sell over 100,000 copies and to land on "Billboard" charts at number 49. Prosen promoted the group heavily, getting them a headlining spot on Dick Clark's "American Bandstand" alongside Jerry Lee Lewis. Simon and Garfunkel shared approximately $4,000 from the song – earning two percent each from royalties, the rest staying with Prosen. They released two more singles on Big Records ("Our Song" and "That's My Story") neither of them successful.
