From an initial Symbolist bent, he developed a distinctive, lunfardo-rich style from an early age, and by 1925 he had his first piece, Pompas de jabón, sung by Carlos Gardel.
Also prolific as a writer, he published three volumes of lyrical poetry (Canciones grises, 1926; La luna del bajo fondo, 1940; and Viento que lleva y trae, 1945), three biographical and historical books (El debut de Gardel en París, La historia del tango en París and Mis memorias), some theatrical works (La epopeya del tango and La baba del diablo, both co-written with Félix Pelayo, and El romance de dos vagos in collaboration with Germán Ziclis) and the narrative pieces El cantor de Buenos Aires, with Alberto Ballerini, and Los cuentos de un príncipe with Martín Lemos.
As a recognition to his career, he was declared Illustrious Citizen of the city of Buenos Aires in 1987, and Emeritus of Argentine Culture in 1996.
Los mareados has enjoyed several revivals; it has been part of Mercedes Sosa's repertoire since the 1980s, and was also covered by Roberto Goyeneche and Andrés Calamaro.
Another Cadícamo lyric, Por la vuelta ("[A toast] to [our] return") is a mirror image of Los mareados: two former lovers meet a year after splitting up, find that their mutual friendship has survived their estrangement, and agree to drink to that.
