Watch FilmoFlix. Scott Wilson plays Jimmy Ray in 'Don't Let Go'. He's a Rockabilly star who's a legend both because of his great hits and because he gave up music very young when his brother was killed. Now, years later he has two sons and they have a band. Jimmy Ray is an alcoholic, still consumed by his grief and angry with his sons for wanting to play music. His wife, Katharine Ross, tries to mediate.
