Help looking for song/artist

Many, many, MANY years ago...early seventies ( I think!)...I heard a song on the radio that has haunted me ever since. The only lyrics of the song that I can remember are: 'America, what have you done? America, where have you gone?
Can anyone help identify this song?

"Voice of America" by Steven Van Zandt ?? Early 80s
