e used the nom de plume Alcázar when he worked for the jolly press of his city, Barcelona, back in 1920.

With maestros J. Demon and Junoy he wrote the operetta Las Pobres Millonarias.

He also wrote the «guignol» El Tango de la Cocaína; parodies; «sketches» and revue scenes, most them premiered at the city of Barcelona. In 1921 he wrote his first song, "La Telefonista", and he was so successful that he decided to fully venture into show business.

«My relationship with the late Carlos Gardel began in the Odeon studios where we were introduced. Despite his short stay in Barcelona we became close friends. I was attracted, from the very beginning, by his great friendliness and natural simplicity in spite of his fame. He, with his characteristic frankness, asked me if I had some song that would fit with the genre he sang. I understood that his interest was genuine, and with the same frankness I told him that I had a couple of things that would be easily suitable for guitar. One of them, “Por un cariño”, the other: “Oiga patrón”. I warned him that both had been premiered and recorded by famous singers. Gardel did not care much about this and we made an appointment at the Hotel Victoria where he was staying. There I made him know the two songs which he liked very much, so much so that a few days later he premiered them in one of his succesful appearances at the Barcelona Theater, and soon he recorded them. The tango “Oiga patrón”, with which he achieved a true creation, was spoiled by a defective pressing and was not released. It was impossible to make a new recording because by that time Gardel was no longer in Spain. When we parted I promised to write more lyrics that he himself would musicalize and that I would send him to Editorial Perrotti in Buenos Aires. So I wrote for Carlos the lyrics of “La huerfanita”, tango, and “Campanita de oro”, an Argentine waltz.

«It took me some time to write them, and when I was about to send them I knew, to my dismay, that he had tragically died. Later the famous Argentine composer, author of “Por el camino (Zamba del boyero)”, “A la luz del candil”, etc., Carlos Vicente Geroni Flores, that passed away a few years ago in Portugal and who was also a great friend of mine, wrote the music for these two lyrics». This was what the Catalonian songwriter said in November 1966 about his memories of Carlos Gardel.

Alcázar was born in Barcelona on September 24, 1898 and there he died on December 28, 1975.
