¡Ay, Jalisco, no te rajes!

or in English Jalisco, don't back down is a Mexican ranchera song composed by Manuel Esperón with lyrics by Ernesto Cortázar Sr.

[3] In their book Writing Across Cultures: Narrative Transculturation in Latin America, Ángel Rama and David Frye posit that the song portrays the common stereotype of Jalisco being "a paradigm of 'Mexicanness'.

[3] The song has been covered by many different artists including Vicente Fernández,[5] Aidá Quevas, Plácido Domingo,[6] Lola Beltrán,[7] Julio Iglesias,[8] Trío Los Panchos,[9] El Charro Gil y Sus Caporales,[10] Francisco Canaro[11] Jorge Negrete his grandson Lorenzo Negrete and Pedrito Fernández.

This success quickly inspired a German vocal version titled "Gaucho Mexicano" by Renate & Werner Leismann which turned out to be a smash hit in both countries.

[citation needed] Other notable artists to record this version of the song include Edmundo Ros,[19] The Fleetwoods,[20] Santo & Johnny,[21] Roland Shaw,[22] and Vic Schoen.
