The trio scored a major European hit in 1977 with their discofied remake of "Black is Black," sometimes also known as "Disco Sound"/"Black is Black." The Belle Epoque version was a top ten hit in many European countries and a number 2 in the UK Singles Chart. The song also became a number 1 hit in Australia in 1978.
In the U.S., Belle Epoque is better known for another song, "Miss Broadway," which charted at number 26 on the U.S. R&B chart and at number 92 on the Billboard Hot 100 in 1978. "Miss Broadway" and "Black is Black" both rose to number 21 on Billboard's "National Disco Action Top 40" chart in summer 1977.
Other hits in continental Europe followed into the late 1970s. Lenton began recording solo again in 1983, although she has worked with contemporary music producers to craft remixes of "Black is Black" and "Miss Broadway."
