MELBOURNE: Australian singer Keith Urban and his actress-wife Nicole Kidman sang ‘Amazing Grace’ for sick children at Monash Children’s Hospital here.

The couple performed an emotional version of ‘Amazing Grace’ in front of patients, their families and members of staff of the hospital June 13, reportedly.

The Grammy Award-winning Urban whipped out his acoustic guitar and started the well-known tune, while Kidman, 46, stood to the side singing along to all of the words.

She watched over her husband proudly in a black pullover and grey skirt, while everyone else around them recorded the unique performance by the husband and wife duo on personal devices.

The couple, who married in 2006 and have children — Sunday, 5, and Faith, 3 — had also performed earlier in 2010 at the G’Day USA ball and sang Men At Work’s ‘Down under’.
