"De Cuando Estuve Loco" (When I Was Crazy) is a song by Joan Manuel Serrat, a Spanish singer-songwriter. The lyrics describe the memories and remnants of a time when the narrator was "crazy" or reckless. In the song, the narrator lists various items and experiences that remind him of his past state of mind. He mentions keeping a "carné de majara" (a card of craziness) in his wallet, a detailed plan of hell, a sky with piranhas and leaks, a record in the police station, a jar of colorful pills, and a letter with which someone bid farewell to him. The narrator also mentions leaving behind suburban areas, air to breathe, and traffic lights, and heading south, disregarding other directions. He refers to the sun being imprisoned on the terrace and his journey south in search of spiral-like kisses. The song continues with the narrator mentioning his past state of mind and possessions. He talks about keeping a couple of grams of delirium, in case the "sane" people attack with their reason, as well as a strong wind, and the habit of writing love rhymes on walls. He also mentions his tendency to search for the person he loves among other women who keep him company during low moments. The lyrics express the narrator's desire and obsession for a person referred to as "you" or "nenúfar" (water lily) who survives in stagnant waters. Whenever he touches their petals, sparks fly, wires cross inside him, and his emotions get heightened. The narrator writes this song from a service area where only gasoline is offered to him. He invites the person he yearns for to call him collect from a corner payphone. Overall, the song captures the nostalgia, longing, and remnants of a passionate and tumultuous period in the narrator's life. It reflects on the emotions, experiences, and possessions that still remind him of his past "crazy" self.
