Marti Pellow (born 23 March 1965) has been the lead singer of the Scottish pop group Wet Wet Wet since their formation in 1982. He has also recorded solo material.
Mark McLachlan was born in Clydebank on 23 March 1965. In 1982, at the age of seventeen, McLachlan formed a band with three friends from Clydebank High School. The friends were Tommy Cunningham, Graeme Clark and Neil Mitchell, and the band's name was Vortex Motion. This was subsequently changed to Wet Wet Wet, a title taken from the Scritti Politti song, "Gettin, Havin' and Holdin'". McLachlan also changed his birth name in favour of the stage name Marti Pellow.
Pellow enjoyed success with Wet Wet Wet throughout the late 1980s and 1990s. However, in 1997 drummer Tommy Cunningham left the band and its success waned immediately. Pellow was by this time suffering from an addiction to heroin. On finally beating the drug, he stated: "It was textbook. I couldn't function without it. But there's no romantic side to heroin – it's no good."
