He studied piano and violin at the Royal Scottish Academy of Music and Drama in Glasgow before going on to become keyboard player in the live line-up of Stiltskin, a rock band with the number 1 hit single "Inside" in the UK in 1994.
Duguid has since appeared on several albums by Stiltskin's old vocalist Ray Wilson, who for a short time in the late 1990s was lead singer with Genesis.
In 2006 he began writing songs with singer Louise Rutkowski, 7 years later in 2013 had finished an album of work (Diary of a Lost Girl) which was funded by Pledge Music and finally released in 2014.
