Brief biography via Wickipedia 2010.

Seán Potts was one of the founding members of The Chieftains. He was great friends with fellow band member and whistle player Paddy Moloney, and they often went around Dublin playing in sessions and gigging during the 1950s. In 1962, Potts helped form The Chieftains. He briefly left the group in 1968 for a contract with Gael-Linn Records but returned to play for the band soon after. He was primarily a whistle player, although he also played the bodhrán and bones. He played with the band until 1979, when the pressures of the music scene (and touring) prompted him to leave the band for an easier life.

Before The Chieftains, Seán Potts was an original member of Seán Ó Riada's group "Ceoltoirí Chualann". After The Chieftains, Potts did a lot of radio work for RTE and founded Bakerswell. In 1972, while still with The Chieftains, Potts and Paddy Moloney, along with Peader Mercier (another Chieftains member) recorded an album called Tin Whistles where both Potts and Moloney played just tin whistle tunes accompanied by a bodhrán to show the versatility of the instrument in the hands of two accomplished masters.
