Diageo currently owns the Johnnie Walker whiskey brand, which was first produced in the Scottish town of Kilmarnock in East Ayrshire. John Walker, a grocery store owner, created the brand initially. With sales of the equivalent of approximately 223.7 million 700 ml bottles in 2016, it is the most widely available mix of Scotch whisky in the world, available in practically every nation (156.6 million litres). Johnnie Walker Red Label was Winston Churchill's preferred whiskey, and he drank it all day long while mixing it with a lot of water. Christopher Hitchens, a writer for Vanity Fair, liked Johnnie Walker Black Label mixed with Perrier effervescent mineral water and called it 'Mr. Walker's Amber Restorative.' US President Richard Nixon loved Johnnie Walker Blue Label; he frequently paired it with ginger ale and a slice of lime. From Amanda Marshall to ZZ Top, several musicians have made mention of Johnnie Walker in their compositions. The narrator of Elliott Smith's Oscar-nominated film 'Miss Misery' says that Johnnie Walker Red helps her get through the day. Because Zakk Wylde loved Johnnie Walker Black Label whiskey, the heavy metal band Black Label Society was given that moniker. In 'I Drink Alone,' George Thorogood makes a reference to 'Johnny Walker and his brothers Black and Red.' The name also appears in Passenger's song 'Remember to Forget.'
