A peek beyond the big hits will upend any preconceptions about John Denver. Sure, he's the all-American boy with songs full of sunshine, but he's also the lonesome balladeer who lets his broken heart bleed all over the gorgeous melancholy of “Like a Sad Song.” And wholesome image notwithstanding, Denver could still offer up a randy, bluegrass-fueled tune like “Baby, You Look Good to Me Tonight.”
