He had 39 Top 40 hits in the late 1950s and early 1960s as a solo performer, or with the Belmonts and the Del-Satins. He is best remembered for his signature hit songs "Runaround Sue", "The Wanderer", "Ruby Baby" and "Lovers Who Wander", among others.

Doo-wop is a subgenre of rhythm and blues music that originated in African-American communities during the 1940s, mainly in the large cities of the United States, including New York, Philadelphia, Pittsburgh, Chicago, Baltimore, Newark, Detroit, Washington, D.C., and Los Angeles. It features vocal group harmony that carries an engaging melodic line to a simple beat with little or no instrumentation. Lyrics are simple, usually about love, sung by a lead vocal over background vocals, and often featuring, in the bridge, a melodramatically heartfelt recitative addressed to the beloved. Harmonic singing of nonsense syllables is a common characteristic of these songs. Gaining popularity in the 1950s, doo-wop was "artistically and commercially viable" until the early 1960s and continued to influence performers in other genres.
