Let's make this birthday one to remember.

58 years old (Born on April 02, 1967)

Happy Birthday, Greg! You're an all-star guitarist whose riffs have rocked generations—proving once and for all that the years may pass, but your music stays as fresh as ever. From Grammy-winning hits to unforgettable stage moments with Smash Mouth, you've truly made every day feel like we're "Walking on the Sun."

Here's hoping this birthday brings you more joy than a sold-out concert crowd singing along to "All Star." May your year ahead be filled with endless creativity, laughter louder than backstage antics, and success brighter than those iconic sunglasses of yours. Keep rocking—you've still got it!
