The country icon has released a freshly recorded version of "Light of a Clear Blue Morning," bringing together Lainey Wilson, Miley Cyrus, Reba McEntire and Queen Latifah for a collaborative take that leans into the song's original promise of resilience and renewal. The reimagined track arrives ahead of Parton's January 19 birthday and is out now, accompanied by a music video.
