Let's make this birthday one to remember.

47 years old (Born on September 12, 1977)

Happy Birthday, Jeff Irwin! You're the musical Swiss Army knife—mastering more instruments than most of us can name. From rocking stages alongside Counting Crows to effortlessly blending genres with countless artists, your talent is as timeless as Adam Duritz's hairstyle.

Whether you're strumming strings or tickling ivories, you always hit the right note (and occasionally a hilarious wrong one). Here's hoping this year brings even bigger gigs and fewer broken guitar strings mid-solo. Keep making music magic—and remember: age is just another instrument you've mastered beautifully!

Cheers to many more years of epic jams and unforgettable moments!
