The stunning live (LIVE!) performance marked the sisters’ first performance together since 1986, when they performed a “Sisters Are Doing It For Themselves” cover on Young Talent Time.

“It’s amazing,” said Kylie. “We’ve been excited and a little bit nervous because it’s a very special moment for us.” Below, watch the global megastars reunite for their first TV performance in nearly three decades and celebrate the Australian “summer Christmas” with a hot new track.
