LOS ANGELES (AP) — Brian Wilson, Vince Gill and Graham Nash are among those who will discuss the impact of the song “I Hope You Dance.” The Hallmark Movies and Mysteries Channel is planning a Thanksgiving night special called “I Hope You Dance: The Power and Spirit of Song.” Lee Ann Womack, who recorded it originally, will tell stories about the creation of the song. The special will be released on DVD on Dec. 1, and a companion book comes out that same day.
