While Washington, D.C. prepared for its largest-ever Fourth of July fireworks display this weekend, Gary Sinise carried something quieter into the celebration: a song written by his late son.

Sinise, in D.C. to narrate content for both the Capitol's "A Capitol Fourth" broadcast and CBS's July 4th special, shared that "Triumphant" - a piece composed by his son Mac Sinise alongside collaborator Oliver Schnee - would be featured as part of the tribute marking America's 250th birthday. Mac, a composer, died in January 2024 of chordoma, a rare bone cancer, at just 33 years old.

It's not the first time Sinise has kept his son's music alive publicly. Earlier this year, two of Mac's compositions were performed by the National Symphony Orchestra at PBS's "National Memorial Day Concert," a moment Sinise called "very special." He's continued producing posthumous volumes of Mac's album "Resurrection & Revival," and this November, he'll release a book chronicling the family's journey: "Graceful Warrior: The True Story of a Son, a Father and a Family Who Carried Each Other Through."

Reflecting on the weekend's celebration, Sinise wrote that watching fighter jets rehearse their flyover over the nation's capital left him thinking about sacrifice on a larger scale - the "thousands and thousands" of Americans buried in military cemeteries at home and abroad, and the families, like his own, who carry loss forward. "We have so much to be thankful for, not the least of which are the men and women who defend our country and protect our cities," he wrote, adding that his foundation works daily to support those who've served and the families who've sacrificed alongside them.

For a man who has spent four decades honoring other families' losses, this Independence Day carried his own son's voice into the celebration - a reminder that gratitude and grief often share the same room.
