"Time to Say Goodnight" is a Sesame Street song that parodies "Con te partirò" (also known as "Time to Say Goodbye"). Andrea Bocelli sang most of the song to Elmo as a bedtime lullaby to help him fall asleep. The lyrics have been adjusted from the original (made famous as a duet by Bocelli and Sarah Brightman) to tell the story of Elmo's long, eventful day which has now come to an end. It also becomes a duet when Elmo sings a few lines as well. Unfortunately, Elmo's time in the dream world does not last long, as Bocelli's continued (albeit louder) singing awakens him.
