Let's make this birthday one to remember.

59 years old (Born on May 31, 1966)

Happy Birthday, Johnny Diesel! Another year older and still rockin' harder than ever—clearly your engine runs on pure Hepfidelity. From topping the charts with unforgettable hits to electrifying stages across Australia, you've proven that age is just a number when you're fueled by passion (and maybe some guitar solos).

Whether it's belting out classics from "The Lobbyist" or reminding us why we fell in love with hard rock vocals in the first place, you continue to inspire generations of fans. Here's hoping this birthday brings as much joy as your music has brought all these years—and remember: legends never get old; they simply turn up louder!
