Crystal Gayle already has blue eyes 

I wonder if they were originally brown? Perhaps not --- according to her biography, she and Hubby have been married for many years and get along quite well, so presumably she's never had much occasion to have her significant other cause her to "cry her brown eyes blue".

I could never quite understand how the song "Don't It Make My Brown Eyes Blue" made much sense, since Crystal Gayle already has blue eyes.
