As an old Vietnam hand of the early '60s, I well remember a song sung around the bar of the Majestic Hotel.
To the tune of "Rock of Ages," we sang:

"We are winning, don't you know?
General Harkins, tells us so.
In the Highlands, things are rough.
In the Delta, things are tough.
But the Vee-Cee, they will go.
General Harkins, tells us so."

followed by...
"If you doubt it, shame on you..
MacNamara says so too."

Does anyone know the second verse? I believe there was one.

This was sung in association with "The Yellow Rose of Saigon," which is in the Mudcat archieves.

I have an Iraq version ready to roll, but I wanted to check this out first.
