A man is seen singing into a microphone and playing banjo with a guitar nearby while sitting on a stool at a festival where there are booths featuring items for sale.
Someone is performing at a festival.
Though sing and playing banjo the man is not said to be on stage so we cannot be sure he is performing at the festival
