Let's make this birthday one to remember.

75 years old (Born on December 14, 1949)

Happy Birthday, Cliff Williams! The steady heartbeat behind AC/DC's thunderous riffs and electrifying shows. You've spent decades holding down the rhythm section with effortless cool—proving once again that bassists don't need towering height to rock stadiums worldwide.

From "Back in Black" to recent triumphs like "Power Up," your unwavering groove has kept millions headbanging through generations. While Angus runs wild across stages, you're calmly anchoring chaos into harmony—a timeless reminder that greatness often comes from quiet confidence (and average stature).

Here's wishing you another year of legendary performances, endless applause—and perhaps a step stool for band photos!
