This song was written by Lionel Richie as a tribute to the late Marvin Gaye. Marvin had just passed and Lionel was feeling the loss. He also knew Diana Ross, who was a friend of Marvin's could really do justice to the lyrics of the song. While she was preparing to record the song, Diana's mom passed away. She has since said that she thinks of both Marvin and her mom when performing the song. Here's Missing You by Diana Ross.
