Who are you?

On a stage with a painted backdrop of buildings, a man in a black coat and red sash leans forward, holding a microphone to the ear of a man in a green jacket and black hat, who stands with a wide stance. To their right, three other men in period-style coats stand watching, one of whom holds a microphone and appears to be singing or speaking. The scene repeats in a loop, with the man in the green jacket occasionally moving his head or adjusting his hat.
