He may no longer be the band's frontman but Wet Wet Wet star appeared on Monday's This Morning to perform two of their classic hits.
Scottish singer turned musical theatre star Marti was the group's lead singer for 25 years, fronting them from 1982 until their first split in 1997 and then again from 2004 to 2017.
That meant he was the voice of absolutely massive hits like Sweet Little Mystery, Wishing I Was Lucky and of course huge number 1 Love Is All Around.
Marti revisited his Wet Wet Wet days to sing 90s classics Goodnight Girl and Julia Says, to the delight of hosts Eamonn Holmes and Ruth Langsford.
Born on March 23, 1965, Marti is now 55 years old...yes really!!!
While he has now been replaced by Liberty X's Kevin Simm as Wet Wet Wet frontman, Marti has forged out a massively successful career in theatre, with starring roles in countless shows including Chicago, Blood Brothers, The Witches of Eastwick, War of the Worlds and Evita.
He has also released a number of solo albums and toured the country with George Benson.
Teasing his This Morning perrformance on Twitter, he posted: "Up early today and been for a swim. Ready to perform on @thismorning
with our @RuthieeL and @EamonnHolmes, good folks. Doing a bit of Julia Says and a wee bit of Goodnight Girl. Tune in, I will give you a wave."
