The song you are looking for was written by TOM T. HALL. Here are the words as sung and recorded by Jimmy Newman.

November 22nd, 1963

When you sing this song be brave and sing it loud and strong and clear,
John F. Kennedy was not a man to ever speak in fear,
Pick up the flag, march on in peace and pray that there will be
More men like John Fitzgerald Kennedy.

On November 22nd, nineteen-hundred-sixty-three,
A sunny day in Texas in a town they call Big D,
A man was killed who changed the course of history,
His name was John Fitzgerald Kennedy.

He was riding in a motorcade that sad and fateful day,
Mrs. Connelley turned to him with a voice so proud and gay,
She pointed out that people here had treated him real nice,
Minutes later bullets took his precious life.

Mrs. Kennedy cried, "O, no." and she caught him as he fell,
What the world lost at that moment only history can tell,
They rushed him to the hospital---took five minutes on the way,
As the word flashed 'round the world to stop and pray.

It was over in just minutes; John F. Kennedy was dead,
Disbelief, shock and sorrow; the people bowed their heads,
Mrs. Kennedy stood by him as the tears came to her eyes,
Put her ring upon his hand and then kissed him goodbye.

The pens of man will scribble on in sad futility,
Perhaps a paragraph or two will touch reality,
John Kennedy was proud and brave and his story has been told,
May his home be blessed and may God rest his soul.

Sing the first verse once more.
