All those days of sore lips, clogged spit valves and muddy feet are about to pay off. Netflix is looking to cast people with marching band experience in an upcoming episode of the network's hit show, Stranger Things.

"We are looking to cast males & females who have had or currently are experienced in participating in a marching band!" a casting notice for the show reads. "You will actually play 2 songs with us (so you must know how to play your instrument)."
