While Jimmy Webb and Glen Campbell are one of the most successful writing-singing teams ever, they haven't always been of like mind. For instance, there's this signature chart-topping hit released at the height of the Vietnam War – written and originally recorded (by Hawaiian pop star Don Ho) as an anti-war song. But Campbell tweaked a few lyrics to introduce ambiguity, underscored by surging strings and upbeat tempo, while performing the song in uniform in the video. Nevertheless, the line that jumps out is, "I am so afraid of dying." Four decades later, the rock band R.E.M. did a response song called "Houston."
