Grammy-nominated singer and songwriter Matthew West’s viral holiday hit ‘One Last Christmas‘ has inspired a movie called ‘The Heart of Christmas‘ that will premiere Sunday, December 4 on GMC. Based on a true story, the film revolves around a Central Illinois community that decorated their houses for Christmas several weeks early for a two-year-old boy battling a rare form of leukemia.

West’s new holiday album, ‘The Heart of Christmas,’ is out now and features appearances by Grammy winners and nominees Vince Gill, Amy Grant and Mandisa from ‘American Idol.’
