Ronan Keating completed the Boyzone line-up at a charity ball on Saturday (21Nov09) by inviting late bandmate Stephen Gately's husband on-stage.
The Irish boyband - including Keating, Keith Duffy, Mikey Graham and Shane Lynch - attended the Emerald and Ivy Ball in London and they were joined by grieving widower Andrew Cowles to pay tribute to Gately.
Keating - who founded the event to raise funds for a cancer charity - told the crowd the band felt whole again when they had Cowles on-stage with them.
He said, "With you being here tonight, the four of us, Boyzone, feel like five."
Gately died at their Spanish home in October (09). A post-mortem examination ruled the No Matter What star suffered from a build-up of fluid on his lungs.
