Producer David Foster re-arranged the song as an R&B ballad. Her record company did not feel a song with an a cappella introduction would be as successful; however, Houston and Costner insisted on retaining it. When Parton heard that Houston was using Ronstadt's recording as a template, she called Foster to give him the final verse, which was missing from the Ronstadt recording, as she felt it was important to the song.
