A popular hit in the 1960's, during the Vietnam War, Staff Sargeant Barry Sadler with: "Silver Wings." On satellite, old Ed Sullivan shows come on and I taped Sadler singing this one (yes, that's how lifeless my life is!!).

Another one, The Singing Nun, Jeaninine Deckers, Soeur Sourire ("Sister Smile"), with the song "Dominique" in 1963. Very popular at the time.

There was also a Japanese language hit on American charts in the 1960's which I can't quite remember right now.
Big hits but one time wonders.
