Westlife’s 25 Years of Hits – The Anniversary World Tour reaches Halloween at The O2 Belfast on 31 October 2026, part of their extended residency. The group’s set draws together their pop and ballad history, threading older singles through to tracks from "Wild Dreams" and beyond. Ana Sky returns as support, keeping the line-up consistent across the Belfast stretch. With several nights already completed and more still to come, this show captures the tour mid-residency, as the band refine transitions, visuals and arrangements to suit the arena’s scale and returning crowds.
