Garth Brooks has filed a breach-of-contract lawsuit to recover a $500,000 donation he made to a hospital in his hometown of Yukon, Okla. The litigation involves the naming of a building at the Integris Canadian Valley Hospital. The lawsuit claims Integris representatives contacted Brooks’ father, Ray, in late 2003 or early 2004 to solicit a donation to the hospital to honor the singer’s mother, Colleen, who died in 1999 following a battle with cancer. The suit claims Integris officials “courted [Garth] Brooks seeking a substantial donation” while promising a building would be named for his mother. Brooks donated the $500,000 in late 2005, but the suit alleges that in September 2008, hospital officials informed him the donation “would be used for what Integris had ‘earmarked’ the money for without further discussion.” Although the lawsuit was reported nationally on Wednesday (Dec. 16), it was filed in district court in Rogers County, Okla., on Sept. 21.
