Libiamo ne'lieti calici (Drinking Song) is the most famous duet from Verdi's "La Traviata" , one of the most well known fragments of opera around the world, and an obligatory performance (as is this opera itself) for any great tenor. The song is categorised as a Brindisi, which encourages alcoholic drinking. The title La Traviata means literally The Fallen Woman, or perhaps more figuratively, The Woman Who Goes Astray. This video also features images of various opera houses around the world.
