The singers were among several musical groups that participated in the fifth annual Festival of Trees hosted by Hospice of St. Mary’s at the Dr. James A. Forrest Career and Technology Center in Leonardtown. The hospice center also auctioned items, such as the trees in the background, to support patient care.
