Crystal Gayle had her first hit single, “I’ve Cried (The Blue Right Out of My Eyes),” in 1970, but it would be six years before she topped the country chart with “I’ll Get Over You” – and seven years till she released what would become her signature, “Don’t It Make My Brown Eyes Blue.” Forty years ago this week, on June 24th, 1977, “Brown Eyes” was the first single released from Gayle’s fourth LP, We Must Believe in Magic.

Take a look back here at the song that made her a household name and a Country music legend.
