Westlife 25 - The Anniversary World Tour

Westlife 25 - The Anniversary World Tour is a concert by the Irish pop group Westlife at The O2 in London, marking the band's 25 years since their formation.

Westlife are an Irish boy band formed in 1998 in Sligo. The group records pop, pop rock and pop opera music and released their first album, « Westlife », in 1999 on Universal Music Group. The band's name is attached to this anniversary tour, which brings their music to London's O2 arena.

The bill also includes Ana Sky, listed as a supporting act on the concert. The programme is built around Westlife's catalogue, with the anniversary title pointing to a retrospective outline of the band's career, though the individual songs in the set are not detailed here.

The O2 hosts concerts and shows in London, and this is a pop-oriented evening suited to listeners who follow Westlife's records and to those attending the band's anniversary celebrations.
