Okay kiddo, have you ever heard music that is played by people using musical instruments like guitar, banjo, and drums while they sing songs? That's what we call a band. They make lots of people happy by playing their music.
Now, a bush band is a type of band that plays music that comes from the countryside or the "bush" as we call it. They play songs that usually have a very lively beat and are great for dancing. People who live in the countryside love listening to bush bands because it reminds them of their home.
Sometimes, bush bands might also wear special clothes that represent the countryside, like cowboy hats or boots. They might also have dancers who wear colorful dresses and twirl around while the band plays. It's a really fun experience!
So, that's what a bush band is - a band that plays lively music from the countryside and makes lots of people happy!
