“Obvious” is the third and final single released from Westlife’s fourth studio album, Turnaround. It was written by Carl Björsell, Carl Falk, Didrik Thott, and Sebastian Thott under their stage name Pilot, Savan Kotecha, and Andreas Carlsson. It was produced by Jake Schulze, Kristian Lundin, and Karl Engström, with additional production by Quiz & Larossi.
“Obvious” peaked at number three on the UK Singles Chart, but marked the departure of Brian McFadden from the band. The band originally planned to write a farewell song for Brian, as it was his choice to leave, however, due to tour rehearsals and TV appearances, it was decided “Obvious” would be released as a single instead. However, as a tribute, CD2 features a medley of Brian’s favourite Westlife songs.
