Let's make this birthday one to remember.

85 years old (Born on July 17, 1939)

Happy birthday, Spencer! Let's raise a glass—or maybe just play a raucous air guitar—to celebrate the legendary guy whose music put countless feet tapping and hearts beating faster. From hitting it big with timeless classics like "Gimme Some Lovin'" to rocking stages around the globe, your groove has proven utterly infectious.

Even after decades in music, you still have us belting out tunes at traffic lights or reviving vintage dance moves at parties—often embarrassing ourselves but always laughing. May your day be as rock-solid as those unforgettable beats you've gifted us all these years. You keep on running (and having fun)!
