"Puttin' On the Ritz" is a song written by Irving Berlin. He wrote it in May 1927 and first published it on December 2, 1929. It was registered as an unpublished song August 24, 1927 and again on July 27, 1928. It was introduced by Harry Richman and chorus in the musical film Puttin' On the Ritz (1930). According to The Complete Lyrics of Irving Berlin, this was the first song in film to be sung by an interracial ensemble. The title derives from the slang expression "to put on the Ritz", meaning to dress very fashionably. This expression was in turn inspired by the opulent Ritz Hotel in London. Hit phonograph records of the tune in its original period of popularity of 1929–1930 were recorded by Harry Richman and by Fred Astaire, with whom the song is particularly associated. Every other record label had their own version of this popular song (Columbia, Brunswick, Victor, and all of the dime store labels). Richman's Brunswick version of the song became the number-one selling record in America. The song received renewed popularity in 1982 when Taco, a Dutch musician, recorded and released a new version of the song. Taco's version was accompanied by a music video, which aired on MTV and other music video networks and programs. Kenny Yarbrough also recorded a cover of the song; this version was used as theme music for the short-lived 1991 sitcom Top of the Heap. Musical structure The song is in AABA form, with a verse. According to John Mueller, the central device in the A section is the "use of delayed rhythmic resolution: a staggering, off-balance passage, emphasized by the unorthodox stresses in the lyric, suddenly resolves satisfyingly on a held note, followed by the forceful assertion of the title phrase." The marchlike B section, which is only barely syncopated, acts as a contrast to the previous rhythmic complexities. According to Alec Wilder, in his study of American popular song, for him, the rhythmic pattern in "Puttin' On the Ritz" is "the most complex and provocative I have ever come upon." Lyrics The original version of Berlin's song included references to the then-popular fad of flashily dressed but poor black Harlemites parading up and down Lenox Avenue, "Spending ev'ry dime / For a wonderful time". In the United Kingdom, the song was popularized through the BBC's radio broadcasts of Joe Kaye's Band performing it
