Born in 1964 in Glasgow Scotland to a musical family, Ewen began taking piano lessons at 8 years old, inspired by a Beatles-singing mother and a choir-leading, saxophone-playing father! Singing competitions and local talent contests followed, but it was not until his teenage years that the seductive shape and sound of the bass guitar soon became the focus of Ewens' musical aspirations.
From the early 1980's, Ewen began playing in a variety of Glasgow-based bands and some jazz residencies throughout Scotland until, after some gentle persuasion from their drummer, joined newly-signed Deacon Blue in the autumn of 1986 and remained in the band until 1994. The band enjoyed huge world-wide success with over four million in album sales, twelve UK Top 40 singles, two number one albums, TV, radio, and tours all over the world.
1997 saw Ewen join the ground-breaking folk/crossover band Capercaillie, with whom he is still an influential member.
