I'm Old Fashioned (ballet): I'm Old Fashioned (The Astaire Variations) is a ballet made by New York City Ballet balletmaster Jerome Robbins to Morton Gould's adaptation of a theme by Jerome Kern, “I'm Old Fashioned,” to a Fred Astaire and Rita Hayworth sequence from the film "You Were Never Lovelier".

Just an Old Fashioned Love Song: Just an Old Fashioned Love Song is a studio album by Paul Williams, released in 1971.  Notable songs, that were hits for other artists, on the album include "(Just An) Old Fashioned Love Song", "We've Only Just Begun", "Let Me Be the One" and "When I Was All Alone".

Gimlet (cocktail): The gimlet (pronounced with a hard 'g') is a cocktail made of gin and lime juice.  A 1928 description of the drink was: "gin, a spot of lime, and soda".  The description in the 1953 Raymond Chandler novel "The Long Goodbye" stated that "a real gimlet is half gin and half Rose's lime juice and nothing else".  This is in line with the proportions suggested by "The Savoy Cocktail Book" (1930) which specifies one half Plymouth Gin and one half Rose's Lime Juice Cordial.  However, modern tastes are less sweet, and generally provide for at least two parts gin to one part of the lime and other non alcoholic elements (see recipes below).

An Old Fashioned Love Song: "An Old Fashioned Love Song" is a 1971 song written by Paul Williams and performed by the American pop-rock band Three Dog Night.

It was Three Dog Night's first record to top the U.S. easy listening chart.  It reached number two in Canada.  Its lyrics suggest the straightforward and melodic nature of the tune: "Just an old fashioned love song / Comin' down in three part harmony / Just an old fashioned love song / One I'm sure they wrote for you and me".

Gin and tonic: A gin and tonic is a highball cocktail made with gin and tonic water poured over ice.  It is usually garnished with a slice or wedge of lime.  The amount of gin varies according to taste.  Suggested ratios of gin to tonic are between 1:1 and 1:3.

It is then rolled up and placed in a brine for a number of days, before being placed in a special press, cooled, and sliced thinly.  It is often use on "rugbrød" to make the traditional Danish open-faced sandwich, "smørrebrød", usually garnished with a thick slice of "sky" and rings of raw onion.
