The Australian Masters Games kick off in Canberra this weekend, bringing thousands of competitors to the capital, and a surprise musical treat. A supergroup of iconic Aussie artists, including Wendy Matthews, Russell Morris, Jack Jones, and Rai Thistlethwayte, will perform at the opening ceremony on Saturday night at the National Museum. The group, cheekily named The Sopranos, promises a setlist packed with hits and high energy.

While the gig is technically a private event, there’s a tip for fans hoping to catch a glimpse: the soundcheck is happening during museum hours. So if you’re wandering through the exhibits on Saturday afternoon, you might just find yourself enjoying a free mini concert from some of Australia’s most beloved performers.
