Leon Peek is a founding member of Oui Bis and has played with members of the band in previous incarnations for over a decade. These incarnations include The New Potatoes, The Band with No Name later known as Swat the Flea, Tuberville and the current Oui Bis. The earlier bands focused on either Old Time or Irish reels, jigs, hornpipes, shottisches and waltzes. With Tuberville, Leon supported Steve in writing original tunes as well as variations on the classics. This continues with Oui Bis, where Leon and Steve add other styles to their repertoire including old standards, tin pan alley, and an assortment of jazz and folk music from Latin America, Eastern Europe and Asia Minor as well as more recent compositions from American instrumentalists.
