premise: An older middle-aged man wearing a brown hat is strumming a guitar and singing into a microphone; his female companion is singing into a microphone and playing an instrument also, but the woman's instrument cannot be readily seen. hypothesis: The couple sing and play together nicely, even if the man's brown hat is blocking the woman's instrument.
neutral: They are not necessarily a couple, and they do not necessarily play together nicely. Just because the woman's instrument cannot be seen, does not mean that the man's brown hat is blocking it.
