Tee Set was a Dutch pop-rock band that achieved international acclaim in the late 1960s and early 1970s. Formed in 1966, the band was led by Peter Tetteroo, whose distinctive voice played a significant role in their unique sound. With influences ranging from beat music to psychedelic pop, Tee Set is best known for their chart-topping hit "Ma Belle Amie," which reached number five on the US Billboard Hot 100 in 1970. Despite their short-lived success, the band's music continues to be noted for its fusion of pop melodies with rock instrumentation.
