There are at least four bands who were called The Monotones: 1) The Monotones were a six-member Doo Wop band in the 1950s United States. They are considered a one-hit wonder, as their only song to reach widespread popularity was the doo-wop hit "(Who Wrote) The Book of Love", which peaked at #5 on the Billboard Hot 100 in 1958. The Monotones formed in 1955 when the seven original singers — all residents of the same housing project in Newark, New Jersey — began performing covers of popular doo-wop songs.
