Toby Keith passed away Tuesday morning at 62 after a battle with stomach cancer. Along with being a singer-songwriter, Keith was a well-known Oklahoma football fan who appeared on “College GameDay” before the rivalry game against Texas.

Known for 20 No. 1 Billboard hits, Keith found celebrity after he released some of his biggest hits, including “Should’ve Been a Cowboy,” “How Do You Like Me Now?!,” “As Good As I Once Was,” “My List” and “Beer for My Horses.”

Keith worked as a roughneck in the oil fields of Oklahoma, then played semi-pro football before he became a singer.

Oklahoma Athletics shared memories of Keith supporting the Sooners, and called it a “profoundly sad reality to exist in a world where Toby doesn’t.”

“He brought life and joy to every room he entered, and our hearts are dimmer today without him. An American icon and a stalwart Sooner. A superstar talent and a fierce friend of our program. We thank him for the unwavering support he always gave, his generosity as a human being and the countless smiles and memories he created here in Oklahoma and around the world.”

In 2017, Keith stopped by Kentucky coach Mark Stoops’ radio show, and offered support for the long-time coach, as well as a prediction that the Wildcats would beat Florida.
