The upcoming Blue Light Disco is for children aged four-to-14 and all are encouraged to dress up in their favourite onesies while they have fun singing and dancing.

The dance floor will be lit up for the dancers, while tables and chairs are available for those who need a break from busting a move.

The cost is $5 per child, and parents and children under four-years-old are free. Tickets can be purchased at the door.

There are a number of vouchers and prizes on the night given out via ticket draws.

Those who pay to enter will receive a ticket in the draw.

The Blue Light Disco will be held upstairs at the Mittagong RSL Club on the Old Hume Highway, Mittagong, from 4.00pm to 6.30pm on August 27.
