Nearly 17 years after losing him to brain cancer, Tim McGraw continues to honor his famous father, Major League Baseball player Tug McGraw, on important dates.

On Sunday, the country crooner took to Instagram to celebrate what would have been the baseball great’s 76th birthday.

Tim, 53, marked the occasion by sharing a photo montage of vintage shots of himself and Tug taken throughout the years. In case you weren’t emotional enough already, the short video is set to his 2004 hit, "Live Like You Were Dying," which was written in his father’s memory.

“Happy Birthday Tugger!” Tim wrote alongside the heartwarming clip (below). “He would’ve been 76 today.... We miss his nuttiness!”

Tim was born to Elizabeth "Betty" Ann D'Agostino out of a short-lived relationship with the then minor-leaguer. The three-time Grammy-winner was raised believing that his stepfather, Horace Smith, was his father. Tim was 11 years old when he came across his birth certificate and learned that his biological father was actually baseball star Tug McGraw.

Though Tug didn’t acknowledge Tim as his son until he was 17 years old, the two formed a close bond that lasted until the elder McGraw’s untimely death.
