Markus "Mark" Michael Patrick Feehily (born 28 May 1980) is an Irish singer and one of the two lead vocalists of the pop vocal group Westlife. Westlife has released twelve albums, embarked on thirteen world tours and won several awards, becoming one of the most successful musical groups of all time. With 15 number one appearances, he is also the highest-charting LGBT performer on the UK Singles Chart. Career 1998–2012: Six as One, IOYou, Westlife Feehily rose to fame as one of the two lead vocalists of the boy band Westlife, the other being Shane Filan. Before Westlife, Feehily, Filan and Kian Egan were members of the self-formed, six-piece, Sligo-based boy band IOYOU, previously named Six As One, which released the single "Together Girl Forever" and songs "Everlasting Love" and "Good Thing". Louis Walsh, the manager of Boyzone, was contacted by Filan's mother and learned of the group. The final line-up, established on 3 July 1998, consisted of Feehily, Filan and Egan from the original line-up, and Nicky Byrne and Bryan McFadden, new members who auditioned from Dublin. Boyzone singer Ronan Keating was brought in to co-manage the group with Walsh, assuming an advisory role. Feehily has sung completely solo on songs for the band in several instances: "Imaginary Diva" (from the World of Our Own album) "Moon River" (from the ...Allow Us to Be Frank album) "Talk Me Down" (from the Where We Are album) "Before It's Too Late" (from the Gravity album). During live performances, Feehily has also sung completely solo for the songs "Oh Holy Night", "Imaginary Diva", "Talk Me Down", "Before It's Too Late" and Boy George's "Il Adore". In addition to being a lead vocalist, Feehily has also co-written several songs, including some with his band members. Feehily has spoken to The Boston Globe of his embarrassment about Westlife's Rat Pack-tribute album, ...Allow Us to Be Frank; he blamed Westlife's label for forcing them to record it after Robbie Williams had success with this type of music. He dismissed the instance as a "weird time" in Westlife's career. Despite this, he has referred to his role in Westlife as "the best job in the world". 2015–2018: Solo career As well as releasing music as part of Westlife, Feehily has also released music as a solo artist, under the name "Markus Feehily" rather than "Mark Feehily", which he was known as in Westlife.
