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"

This upbeat song features in the movies Toy Story and Toy Story 2. While not explicitly a song for goodbye, the following phrases make this lovely song perfect for a farewell: "When the road looks rough ahead And you're miles and miles From your nice warm bed Just remember what your old pal said Boy, you've got a friend in me"
