who sang the original beauty and the beast song

The answer depends on what you mean by “original”:

• In the film: The song “Beauty and the Beast” is sung as a duet by characters Belle and the Beast (voiced by Paige O’Hara and Robby Benson respectively).
• Soundtrack Version: However, the most well-known version is the pop duet by Celine Dion and Peabo Bryson, released as a single for the film’s soundtrack.
• Demo Version: There was also a demo version sung solely by Angela Lansbury, who voices Mrs. Potts in the film. This wasn’t used in the final movie but might be considered an “original” version.
