The Tee Set was a Dutch pop-rock band that emerged in the late 1960s. Characterized by a blend of beat, pop and rock styles, the band was popular both in their native Netherlands and internationally. The band was led by Peter Tetteroo, whose distinctive vocal style was a defining element of their sound. They are best known for their 1969 hit "Ma Belle Amie," which reached the Top 5 on the U.S. Billboard Hot 100 and remains a classic of the period.
