Castille was born to a
Cajun French speaking family. His father was named François Castille. He learned to play the fiddle from his Uncle Cyprien Castille at around the age of 9. After moving around for a while, he ended up in
Pecaniere – a small community near Leonville, LA. Here, he first heard "Jole Blon" by
Harry Choates during a trip to the Silver Slipper, a grocery store and bar. The song inspired him to take up a new style of playing. In the early 1950s, he started playing at Roy's Bar in
Port Barre, LA and local house parties. Also, they played on the KSLO "Amateur Hour" segments on Saturday mornings. ==Festival du Voyageur==
