Which song did Frank Loesser write in 1947 that became a standard for New Year's Eve celebrations?

Frank Loesser wrote “What Are You Doing New Year's Eve?” in 1947, and the song became a New Year's Eve standard.

Loesser was an American songwriter and lyricist best known for works including the musical Guys and Dolls. The song's title poses a romantic question about plans for the coming holiday rather than describing a midnight countdown directly. Its sophisticated melody and conversational lyric helped it become popular with many singers.

The song was introduced by Margaret Whiting, whose recording with the Freddie Slack Orchestra helped establish it. It has since been recorded in many styles, including pop, jazz, traditional pop, and contemporary arrangements.

The song is often confused with “Auld Lang Syne,” the traditional year-end song associated with midnight in many English-speaking countries. They are separate works: Loesser's composition is a twentieth-century popular song, while “Auld Lang Syne” uses words by Robert Burns and a traditional melody. The title's apostrophe and question mark are part of its commonly used form.
