Let's make this birthday one to remember.

77 years old (Born on February 28, 1948)

Happy Birthday, Mike Brady! Another year older and still kicking goals—literally. Your anthems like "One Day in September" and "Up There Cazaly" have become as iconic as meat pies at the footy, proving that your voice is Australia's unofficial soundtrack to sporting glory.

Whether it's belting out tunes on grand final day or inspiring crowds with timeless melodies, you've shown us all how to stay forever young (at least vocally). May this birthday bring you plenty of laughs, good mates around the barbecue, and perhaps another anthem-worthy moment. Keep singing loud—you've truly earned legendary status down under!
