"Silhouettes" is a song made famous by the doo-wop group the Rays in 1957, peaking at number 3 on the U.S Billboard Hot 100. A competing version by the Diamonds was also successful. In 1965 it was a number 5 hit in the US for Herman's Hermits, and in 1990 it was a number 10 hit in the UK for Cliff Richard.

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.
