The version I sing, which I learned from the 48th Assault Helicopter Company in Vietnam in 1966, is called "Phan Rang Tower". Teterboro airfield is in northern NJ near NYC, not in VN of course. I have a cassette tape of civilian pilot Arthur Godfrey(remember him?) singing "Teterboro Tower".

Some of you might be interested in the songs we six VN vets brought back from there or wrote while there, on the 1992 Flying Fish CD "In Country: Folk Songs of Americans in the Vietnam War", still available from Rounder Records.
