Keith Urban's hit 'For You,' which was written for the film 'Act of Valor,' racked up a huge share of artist and publishing royalties for the singer -- to the tune of $300,000. But, instead of keeping it for himself, the star has presented the money to the Navy SEAL Foundation.

Urban took the opportunity to give the whopping check to NSF backstage at his show in San Diego, Calif. on Saturday (Sept. 28). The NSF is a non-profit organization that serves to support SEAL families and their parent commands via immediate, ongoing and unwavering help toward easing financial burdens, establishing support networks and funding command-sponsored activities.

The 'American Idol' judge was, of course, beyond glad to help support the NSF. "I have a deep appreciation for the special bond that all of these families feel towards each other and for the commitment that they have made to all of us," Urban says. "The NSF reminds us to acknowledge the importance and sacrifice that is made each and every day by those serving ‘down range’ as well as their loving families."

Urban's donation will be used in a huge way -- Robin King, CEO of the Navy SEAL Foundation, explains, “The Navy SEAL Foundation is humbled by Keith’s generosity and support of our community and its families. His generous donation will help fund resiliency retreats for 120 SEALs and their families, fund the opportunity for over 500 Naval Special Warfare children to attend summer camp in 2014, where they’ll learn the importance of teamwork, communication, cooperation, goal setting and overcoming adversity."

'For You' is part of the 'Act of Valor' movie's soundtrack, which showcases many other country artists, including Hunter Hayes, Lady Antebellum and Sugarland. Urban is currently on his Light The Fuse Tour in support of his seventh studio album 'Fuse,' which debuted at No. 1.
