THE Gympie Music Muster spirit was well and truly alive on Saturday afternoon, with some of the festival's biggest legends on hand at the Verandah Bar to celebrate the 2018 Partner Thank You Function.

Muster Ambassador and Headliner Troy Cassar-Daley featured among the speakers and performed two songs at the event, getting wife Laurel to lend her vocals and help tell the story of how they became engaged on the campgrounds more than two decades ago.
