Men and women who protect the country will take a turn entertaining on Friday night. The Notables, an Air Force jazz ensemble, will be performing at the Knoxville Middle School Auditorium Friday evening at 7:30pm. The Notables are a part of the Heartland of America band and have been described as a “little big band.” During the concert, they will also share stories from the times that they have served. Over the years, the Notables have performed with Bob Hope, Lee Greenwood, and Wycliffe Gordon. The free concert begins at 7:30 tonight at the Knoxville Middle School. Superintendent Dr. Randy Flack encourages the community to enjoy the free entertainment.
