Details: The band was formed in 1965 in Delft, Netherlands by singer Peter Tetteroo [nl]. Other early members were Gerard Romeyn on guitar, Polle Eduard on bass, Carry Janssen on drums, and Robbie Plazier on keyboard. Their first single released in 1966 on the Delta label, "Early in the Morning", was successful in The Netherlands. The band had a top 10 hit "Don't You Leave" the same year, selling 10,000 copies in it's first week of release. The band underwent numerous changes in it's line-up though the years; the keyboardist Hans van Eijck joined in 1966, replacing Robbie Plazier. Romeyn, Eduard and Janssen left, to be replaced by Ray Fenwick on guitar, Franklin Madjid on bass, and Joop Blom on drums. Van Eijck also left and was replaced by Jan-Pieter Boekhoorn on keyboard (Van Eijck later returned in 1969). Fenwick then left and later reappeared in The Spencer Davis Group. He was replaced by Ferdi Karmelk. Dihl Bennink also joined the band. In 1969, Tetteroo founded their own label Tee Set Records. The group recorded a single in 1969 titled "Ma Belle Amie", which was a hit in their native country, selling over 100,000 copies. The group released an album in the United States on Colossus Records in 1970 titled Ma Belle Amie (the single of the same name listing the artist as 'The Tee Set'), which reached No. 158 on the Billboard 200 chart, just as the single took off in the United States, eventually reaching No. 5. The single sold over 1 million copies, and was awarded a gold disc. The version of "Ma Belle Amie" released in 1970 on Major Minor records in the UK is a different studio version of the song, slower in tempo and beginning in a lower key than the hit U.S. version. In the Netherlands, Tee Set's single "She Likes Weeds" reached No. 1 on the Dutch charts. However, the track was banned in the U.S. because it was said to be referring to drug use, although the title was taken from the film Funeral in Berlin. The follow-up single "If You Do Believe in Love" hit No. 81 in the US and No. 31 in Canada. The group disbanded in 1975, but briefly reunited in 1978 and 1983.
