Did the average medieval European peasant/serf care who was king?

The way I was taught about feudalism, it seems like things were a bit of a long, convoluted and often not continuous chain from king down to serf. With the lack of mass communication at the time and the degrees of separation between a serf and the ruler, I struggle to imagine your average person knowing/caring who their king was. Was the identity or actions of the ruler often relevant information to serfs?
