All Blacks legend Richie McCaw joins The Wiggles on stage for special guest appearance

It seems Richie McCaw has found a new job ... this time donning the black jersey for The Wiggles.

Dressed in a black skivvy, the All Blacks legend made a guest appearance on stage as the fifth Wiggle during their Christchurch concert over the weekend.

Showing off his secret talent, McCaw led The Wiggles with a rendition of 'Scotland The Brave' on the bagpipes.

He later returned to the stage to end the show with the song 'We're All Fruit Salad.'
