The band's earliest influences came primarily from the work of Chuck Berry and the Four Freshmen. Performed by the Four Freshmen, "Their Hearts Were Full of Spring" (1961) was a particular favorite of the group. By analyzing their arrangements of pop standards, Brian educated himself on jazz harmony. Bearing this in mind, Philip Lambert noted: "If Bob Flanigan helped teach Brian how to sing, then Gershwin, Kern, Porter, and the other members of this pantheon helped him learn how to craft a song." Other general influences on the group included the Hi-Los, the Penguins, the Robins, Bill Haley & His Comets, Otis Williams, the Cadets, the Everly Brothers, the Shirelles, the Regents, and the Crystals.
