Dreams Come True - World Of Our Own (1999-2002)
Westlife's first big break came in 1998 when they opened for the Boyzone and Backstreet Boys' concerts in Dublin. Later that year, they won the 'Best New Tour Act' award at the Smash Hits Poll Winners Party. In March 1999, the group released their first single, "Swear It Again" which immediately topped the charts in Ireland and in UK for two weeks. Their second single, "If I Let You Go", released in August 1999 along with the highly acclaimed "Flying Without Wings" (their first 'Record of the Year'), released in October the same year, also followed suit. "Flying Without Wings" was also included on the soundtrack of the Warner Brothers film, "Pokémon 2000". The first album, simply titled Westlife, was released in November 1999 and peaked at #2 in the UK. Ironically, the album was the biggest chart dropper in the music history of UK, falling from #3 to #37. In December 1999, the double a side fourth single was released,"I Have A Dream"/"Seasons In The Sun", knocked Cliff Richard's "The Millennium Prayer" off the top spot and earning them the 1999 UK Christmas number-one single. The fifth and last single from the album, "Fool Again", also peaked at #1. Then, the group went on a short UK and Asian tour in support of their debut album before releasing a second album.
Coast to Coast was released a year after and was another #1 UK album beating the Spice Girls' Forever album. It became the country's 4th biggest selling album of 2000 and is Westlife's biggest selling album to date. The album was preceded by a duet with Mariah Carey on the Phil Collins' classic "Against All Odds (Take a Look at Me Now)" and the original song, "My Love" (the song that bagged their second 'Record of the Year' award). Both singles reached #1 on the UK charts. With this, Westlife broke an unexpected record of having their first seven singles debut at the top of the UK charts, tying with The Beatles. However, in December 2000, they failed to secure their eighth chart-topper in a row with their UK and Ireland only single "What Makes A Man" when kid's favourite, Bob The Builder's "Can We Fix It", was crowned as the Christmas number-one single of that year. Outside the UK/Ireland territories, they have released "I Lay My Love on You" and "When You're Looking Like That" and gained chart success. In 2001, the boys launched their first world tour, "Where Dreams Come True Tour", unofficially nicknamed "The No Stools Tour" due to the group's reputation of performing while perched on stools.
Westlife released World Of Our Own, their third album, in November 2001. "Uptown Girl", "Queen of My Heart" and "World of Our Own" were released as singles, as of which all peaked at #1 in the UK. "Bop Bop Baby" was also released as a single but it peaked at #5 in the UK Singles Chart. In 2002, Westlife went on their second world tour, the World Of Our Own Tour (In The Round)
Unbreakable - Departure of Brian (2002-2004)
The group released their eleventh UK #1 single, "Unbreakable", in 2002. Amidst rumours of a split, Westlife released their first greatest hits album in November that same year entitled, Unbreakable - The Greatest Hits Vol. 1 zoomed all the way to #1 in the UK. The release was followed by the double a side single, "Tonight/Miss You Nights", which debuted at #3 in the UK. At this era, Because Films Inspire... made a TV Documentary titled as "Wild Westlife" directed by Iain MacDonald and starred by the group itself. It reveals how was their musical life on a daily basis and when on tour. In 2003, Westlife went on to their third world tour, The Greatest Hits Tour, shrugging off rumours of a split.
In September 2003, Westlife released "Hey Whatever", which peaked at #4 on the UK Charts. Their fourth studio album, Turnaround, was then released in November, earning the group another UK #1 album. "Mandy", a cover of the Barry Manilow hit, was released in November 2003. Their version won them their third Record of the Year award in under five years. Their version of Mandy is also considered as the highest single leaper to the top (from #200 to #1) in the UK music history. "Obvious" was released as the final single from the album, charting at #3. On 9 March 2004, just three weeks prior to embarking on their fourth world tour, Bryan McFadden left the group to spend more time with his family and work on solo projects. On that day, a press conference was held where all the group's members were present and gave emotional individual speeches. Bryan's final public performance as part of Westlife was at Newcastle Upon Tyne's Powerhouse nightclub on 27 February 2004. He subsequently began a solo career, deciding to revert the spelling of his first name back to its original 'Brian', he released his first solo single, "Real To Me" which entered the UK chart at #1 and soon after, he released his first solo album, "Irish Son" under Sony Music. He went on to release more singles with moderate success.
