Origin

Prior to becoming successful, Egan, Feehily and Filan along with fellow Sligo men Derrick Lacey, Graham Keighron and Michael Garrett, were part of a six-member pop vocal group called Six as One and was later changed to IOYOU in the year 1997. Managed by choreographer Mary McDonagh along with two other informal managers, they released a single titled "Together Girl Forever". Walsh, the manager of the 1990s boy-band Boyzone, was contacted by Filan's mother and came to know about the group. However, the group did not meet Cowell's approval for a record deal with BMG, and thus changes were needed. Cowell told Walsh, "You are going to have to fire at least three of them. They have great voices, but they are the ugliest band I have ever seen in my life." Three members of the band were told they would not be part of the new group, and auditions were held in Dublin where Byrne and McFadden were recruited. The new group, formed on 3 July 1998, was re-named Westside but as the name was already taken by another band, it was later changed to Westlife. In Westlife – Our Story, Byrne revealed he was keen to change the name to West High but the others wanted Westlife. Brian also changed the spelling of his name to Bryan to make it easier to sign autographs. Boyzone singer Ronan Keating was brought in to co-manage the group with Walsh. The band then released an EP titled Swear It Again.
