By W. Derek Russell Daily Journal TUPELO – Few traditions stand the test of time like the GumTree Festival – but even with its many components, celebrating the arts stands at the forefront of the festival’s mission for the past 46 years. Part of that celebration is the annual songwriting competition, and this year is no different. “It’s a great opportunity to showcase regional musicians and singer-songwriters,” said GumTree Museum of Art executive director Belle Naugher.
