Regando literally means "watering" (as in watering plants). However, in the context of this corrido, it takes on a more colloquial and intriguing meaning of "spreading" or "distributing."
The song opens with "andamos regando Correos," which can be interpreted as "we are spreading/distributing corridos." This double meaning makes the word interesting, as it hints at the way these traditional songs are shared and become known, much like seeds being watered to grow.
Tito Torbellino Jr.'s "Mario Aguirre (En Vivo)" is a corrido that tells the story of Mario Aguirre, a figure seemingly involved in the world of cartels and high society. The song opens by setting the scene, mentioning "Corridos clásicos tradicionales" [classic traditional corridos] and then introducing Mario Aguirre.
The lyrics describe Mario as someone with "buen estilo para mandar" [good style for commanding] and someone who interacts with a wide range of people, from "mecánicos y albañiles" [mechanics and construction workers] to "media y alta sociedad" [middle and high society], and even "empresarios y mafiosos" [businessmen and mafiosos]. The song uses the metaphor of a plant, saying "la planta negra creció, Mario la supo regar" [the black plant grew, Mario knew how to water it], suggesting his influence and power expanded significantly, even to the point where "en avión se dio, fruto racimos bajar" [it grew on a plane, fruit bunches came down]. We hear about his connections to "Ismael sextager" and how "de grandes Montes y Juancho lo vieron la última vez" [from great mountains and Juancho saw him the last time]. The tone shifts as the song reveals Mario's passing: "de manos se despidió y para siempre se fue" [he said goodbye with his hands and left forever]. The cartel is in mourning, and the song laments, "jamás lo volverá a ver" [you will never see him again], marking the end of Mario Aguirre's story.
