Born in Dublin, it was as a member of the band Boyzone that he first burst on to the pop scene during the mid-1990s.
Boyzone’s first UK hit, Love Me For A Reason, reached No 2 in the charts in 1995 and by the end of the 1990s the band had enjoyed six UK No 1 singles and three No 1 albums.
Keating has enjoyed success as a solo artist, with hits such as When You Say Nothing At All and Life Is A Rollercoaster.
This is his ninth appearance in the Alfred Dunhill Links Championship.
Says his greatest moment in the Championship was leading after two days in the Team Championship in 2008 with Graeme Storm.
