In honor of National Margarita Day here are some songs about tequila. Tequila is a main ingredient.  It is  made from the blue agave plant, primarily in the area surrounding the city of Tequila northwest of Guadalajara, and in the highlands of the central western Mexican state of Jalisco.   According to Wikipedia, " One of the earliest stories is of the Margarita being invented in 1938 by Carlos "Danny" Herrera at his restaurant Rancho La Gloria, halfway between Tijuana and Rosarito, Mexico, created for customer and former Ziegfeld dancer Marjorie King, who was allergic to many spirits, but not to tequila.
