This duet, between the characters Elphaba and Glinda in the musical play Wicked, is inspired by the story of the Wizard of Oz. It is sung at the end of the play, and reflects on how their friendship has changed them "for good", before they part: "It well may be That we will never meet again In this lifetime So let me say before we part So much of me Is made of what I learned from you"
"Because You Loved Me" was originally written by Diane Warren as a tribute to her father, and the song became Celine Dion's signature song. It is a love-affirming song, whether for family, friends, or a special romance.
True colors by Cyndi Lauper Beautiful friendship affirmation ballad. While not specifically a goodbye song, it is so lovely and easily dedicated to a loved one that is leaving:
"If this world makes you crazy and you've taken all you can bear you call me up because you know I'll be there".
So Long, Farewell This is the classic goodnight song - cheerful and easy to sing along to. From the movie The Sound Of Music, which is also a movie classic, it was sung twice - the first time to say goodnight, the second time to say adieu.
