After a two-year military stint, Wilson settled in Los Angeles, touring the local nightclub circuit before joining the R&B vocal group the Jewels; from there he landed with the Rollers, followed by a stint with the instrumental combo the Souls. In 1966, Wilson signed with manager Marc Gordon, who quickly sought his client an a cappella audition for Johnny Rivers. Wilson was signed to the Soul City imprint and Rivers produced the sessions that yielded the 1968 U.S. R&B hit single "The Snake" (U.S. Pop #27), which became popular on the Northern Soul circuit in the United Kingdom. It also provided Wilson with his only UK Singles Chart hit, reaching #41 in 1975. The minor hit "Do What You Gotta Do" appeared that same year. In 1969, Wilson charted with his cover of Creedence Clearwater Revival's "Lodi" (U.S. #67), and Rivers' own "Poor Side Of Town" (U.S. #75).
