Children Robert Miles
Boyzone are to sing on stage together for the first time since the death of bandmate Stephen Gately.
Keith Duffy, Shane Lynch and Mikey Graham will join Ronan Keating during one of his solo shows.
They're to perform "Gave It All Away" - which features the last vocals Gately recorded before he died.
Fans at the March 11th gig will also be shown a preview of a new Boyzone film.
Ronan says it charts how they coped with the aftermath of their loss and the making of their new album, Brother.
