"Just a Gigolo" is a popular song, adapted by Irving Caesar in 1929 from the Austrian tango "Schöner Gigolo, armer Gigolo", composed in 1928 in Vienna by Leonello Casucci to lyrics written in 1924 by Julius Brammer.
The song was first published by Wiener Boheme Verlag in 1929 and performed by several orchestras in Germany that year, including Dajos Béla's orchestra with the singer Kurt Mühlhardt. In Italy Daniele Serra sang a version entitled "Gigolo", followed by Sirio Di Piramo and his orchestra in 1930, while other countries provided their own versions.[3]

The original version is a poetic vision of the social collapse experienced in Austria after World War I, represented by the figure of a former hussar who remembers himself parading in his uniform, while now he has to get by as a lonely hired dancer. The music features a simple melodic sequence, but nonetheless has a clever harmonic construction that highlights the mixed emotions in the lyrics, adding a nostalgic, bittersweet effect.

The success of the song prompted publishers Chappell & Co. to buy the rights and order an English version from Irving Caesar, a very popular lyricist of the time. Caesar eliminated the specific Austrian references and, in the often-omitted verse (but included in the 1931 recording by Bing Crosby), set the action in a Paris cafe, where a local character tells his sad story. Thus, the lyrics retained their sentimental side but lost their historic value. Popular versions in 1931 were by Ted Lewis, Ben Bernie, Bing Crosby and Leo Reisman.[4]

"Just a Gigolo" appeared in a 1931 film, a 1932 Betty Boop cartoon and a 1993 TV series, all titled after the song. The song was recorded by many musicians of the time, including Louis Armstrong and (in German) Richard Tauber.

The film Schöner Gigolo, armer Gigolo, directed by David Hemmings in 1979, was titled after the first verse of the original lyrics, but the Just a Gigolo title was used for US distribution. In this film, the song was performed by Marlene Dietrich, in her last film appearance.
