Harvey Wallbanger

Make sure you use Galliano L'Autentico, and not Galliano Vanilla. Galliano's flavor profile is mainly vanilla and anise.

If you don't have Galliano, you could play around with the recipe by pairing different liqueurs. Licor 43 for its vanilla flavor mixed with a small amount of anise liqueur (Anís de Mono, Sambuca) could land you a similar flavor profile.

Consider adding a few drops of orange bitters to enhance the orange flavor.

The Harvey Wallbanger was one of the most famous cocktails of the 1970s. This decade is often referred to as "The Dark age of Cocktails" because of the tendency to use premade ingredients (sour mix, sweeteners with mostly high fructose corn syrup and bright colors, and so on).

Per Robert Simonson, the Harvey Wallbanger was likely created as a collaboration between Donato "Duke" Antone and the marketing team for a company which imported Galliano in the US, some time in the 60s.

Antone had a bartending school after being involved in the trade for most of his life. Per his grandson, he had created a cocktail called The Duke's Screwdriver (orange juice, vodka and Galliano) many years before the Harvey Wallbanger exploded in popularity.

It is likely that the marketing team at McKesson Imports Co, which imported Galliano in the US, changed the cocktail's name and came up with a story about how the drink alludes to a Californian surfer named Tom Harvey who frequented Antone's bar.

Allegedly Harvey, after winning a surfing competition, drank this drink so many times that he started banging his head against the wall. The marketing team also came up with a mascot in the form of a surfer.

Galliano was created in 1896 in Tuscany and is named after Giuseppe Galliano, an Italian Officer of the Royal Italian Army.
