"Miss Marmelstein" is a song composed by Harold Rome, first introduced by Barbra Streisand in the Broadway musical I Can Get It for You Wholesale.
The young secretary Miss Marmelstein is a supporting role in the show; in the song she laments everyone addressing her so formally.
The song became the most memorable part of the musical, with Streisand routinely stopping the show.
[1] The song was released as a promotional only single to radio in April 1962 with "Who Knows?"
This marked Streisand's first appearance on a Columbia Records single.
