Do these pensioners have sweeter moves than Pharrell Williams?
Sixty residents and staff from Christchurch's Diana Isaac Retirement Village proved ageing bones and dodgy hips were no barrier to making a banging music video.
The seniors spent four days in May filming the parody to Pharrell Williams' Happy, which they have renamed "80-odd years of Happy".
The song was picked because of its inspiring message about getting the best out of life.
Alister Leckie, 79 - also known as "Al Pharrell Williams" - is the star of the video.
The retired engineer said he loved the experience and didn't hesitate when asked to give it a go.
"Heavens above - you get on and have as much fun as you can," he said.
"It was a great opportunity. I'm not sure why I was chosen but I loved giving it a go.
"I was a bit jiggered by the end of it though."
More than 400 people attended the red carpet premiere of the video at the village on Saturday night.
