Australian rocker Jimmy Barnes and family have recorded their version of Pharrell Williams' hit Happy.
The version features three generations of the Barnes family with Jimmy and Jane heading the group along with daughter Mahalia and grand-daughter Ruby making a rare vocal appearance.
Barnes is using his sites on Facebook, Twitter and YouTube to give fans a special acoustic performance every month.
"We recorded this late last week, and the song that was #1 was Happy by Pharrell Williams, so here you go," Barnes said on his Facebook page.
