FAIR OAKS, Calif. — Kevin Sharp, a country music singer who recorded multiple chart-topping songs and survived a well-publicized battle with cancer, has died. He was 43.

His sister said Sharp died of complications from past stomach surgeries and digestive issues.

Sharp gained fame with “Nobody Knows,” a single on his 1996 debut album, “Measure of a Man.” He released two other albums, “Love Is” in 1998 and “Make A Wish” in 2005. He was a Make-A-Wish Foundation spokesman.
