RMK get in on the happiness

Since 2Day FM used Pharrell Williams' 'Happy' to help promote the launch of their new breakfast show, it has led to a string of people making their own.

Staff at 2Day FM and Christian Hull at SAFM made their versions.

Now voice artist agency RMK have got in on the action, filming their version around the offices. They even organised for voice talent to send in their dancing to add to the final cut.

Lots of people to look out for, including Triple M's Sideshow in the backyard with the kids and a trampoline.
