The label if-by-whiskey refers to a 1952 speech by Noah S. “Soggy” Sweat, Jr., a young lawmaker from the U.S. state of Mississippi, on the subject of whether Mississippi should continue to prohibit (which it did until 1966) or finally legalize alcoholic beverages:
“If you mean whiskey, the devil’s brew, the poison scourge, the bloody monster that defiles innocence, dethrones reason, destroys the home, creates misery and poverty, yea, literally takes the bread from the mouths of little children; if you mean that evil drink that topples Christian men and women from the pinnacles of righteous and gracious living into the bottomless pit of degradation, shame, despair, helplessness, and hopelessness, then, my friend, I am opposed to it with every fiber of my being.
However, if by whiskey you mean the lubricant of conversation, the philosophic juice, the elixir of life, the liquid that is consumed when good fellows get together, that puts a song in their hearts and the warm glow of contentment in their eyes; if you mean Christmas cheer, the stimulating sip that puts a little spring in the step of an elderly gentleman on a frosty morning; if you mean that drink that enables man to magnify his joy, and to forget life’s great tragedies and heartbreaks and sorrow; if you mean that drink the sale of which pours into Texas treasuries untold millions of dollars each year, that provides tender care for our little crippled children, our blind, our deaf, our dumb, our pitifully aged and infirm, to build the finest highways, hospitals, universities, and community colleges in this nation, then my friend, I am absolutely, unequivocally in favor of it.
This is my position, and as always, I refuse to compromise on matters of principle.”
