Master Sgt. Benjamin Park, U.S. Air Force Band bass vocalist, plays a melodica during a Fall 2016 Band performance in Midland, Pa., Oct. 28, 2016. Park played this instrument to the song “Sixteen Tons,” popularized by Tennesssee Ernie Ford in 1955, that narrated the life of a coal miner. This was one of many songs during the performance sung by the Singing Sergeants, the official chorus of the U.S. Air Force Band. (U.S. Air Force photo by Senior Airman Jordyn Fetter)
