Let's make this birthday one to remember.

73 years old (Born on December 01, 1951)

Happy birthday to the legendary Jaco Pastorius! Your groundbreaking bass lines and electrifying performances continue to inspire musicians worldwide. From your iconic solo album that redefined jazz fusion, to your unforgettable collaborations with Weather Report, you've left an indelible mark on music history.

Even today, aspiring bassists strive (and often hilariously fail) attempting "Teen Town" at full speed—proof of how timelessly challenging and brilliant your work remains. Here's hoping you're grooving somewhere cosmic right now; may this birthday celebration be as funky and vibrant as every note you ever played!

Cheers to you, Jaco—the undisputed king of fretless coolness!
