I believe my copy of Louis Armstrong's St James Infirmary was the same we heard that night - Classic Records - 45 - Single. About $30. Well worth the investment in my humble opinion.
You can read up on the history of Louis and the various versions here:
The Wonderful World of Louis Armstrong: 80 Years of St. James Infirmary
I went down to St. James Infirmary,
Saw my baby there,
Stretched out on a long white table,
So cold, so sweet, so fair.
Let her go, let her go, God bless her,
Wherever she may be,
She can look this wide world over,
But she'll never find a sweet man like me.
