Southern A cappella Sound, a four-part harmony group, will be the Saturday afternoon entertainment at the Cotton Festival Sept. 14. The group, made up of ladies from Monroe, Ruston and Grayson, sings in harmony without any instruments, using only their voices to make the bass sound, the tenor, the baritone and the lead parts of each vocal arrangement. They regularly entertain at civic events and charitable functions, sharing the proceeds with scholarship funds, health care and social service programs and the arts and humanities. The group has been a chartered chapter of Sweet Adeline's International since 2006 and also supports its official charity, The Young Singers Foundation. Fair manager Jerry Jordan encourages all ages to hear this unique American art form, and offers those over 65 the opportunity to do so for free. "We are waiving the gate fee Saturday for anyone 65 and older to come out and hear this group and take advantage of everything else the festival has to offer," Jordan said. "This age group can visit the Cotton Festival anytime from 9 a.m. until closing Saturday without a gate fee, but they must bring proof of age." Southern A cappella Sound will perform on the stage of the Boots Farrar Pavilion from 2 p.m. until 4 p.m. Sept. 14.
