I have chosen to do the song, Goodnight saigon by billy joel;

We met as soul mates on Parris Island
We left as inmates from an asylum
And we were sharp, as sharp as knives
And we were so gung ho to lay down our lives

We came in spastic like tameless horses
We left in plastic as numbered corpses
And we learned fast to travel light
Our arms were heavy but our bellies were tight

We had no home front, we had no soft soap
They sent us Playboy, they gave us Bob Hope
We dug in deep and shot on sight
And prayed to Jesus Christ with all our might

We had no cameras to shoot the landscape
We passed the hash pipe and played our Doors tapes
And it was dark, so dark at night
And we held on to each other
Like brother to brother
We promised our mothers we’d write
