Scottish musician Graeme Duffin is an accomplished guitarist and secret member of Wet Wet Wet, contributing to all their work yet never appearing in any of their press.

Duffin joined Wet Wet Wet in 1983, after the departure of Lindsey McCauley, yet he curtailed his press appearances partly due to his pronounced stammer; as a result of dealing with a speech impediment, he worked closely with the British Stammering Association Scotland, gradually rebuilding his confidence and helping others to do so too. Outside of Wet Wet Wet, he joined ex-member Marti Pellow on his solo tour in support of his 2006 record Moonlight in Memphis. Later the same year, his daughter, Esther Duffin, released her debut album as part of Ashton Lane, on which he played guitar, and he would go on to do the same for their second long-player, 2015's Count the Stars. Duffin eventually got around to releasing a solo album, 2020's Spain, a guitar-driven jazz record inspired by the titular country. ~ Liam Martin, Rovi
