Bards, the great travelers and singers from the days of taverns. Gathering folk of all kinds just so they could hear tales from never-ending adventures. They could be exaggerated, but what was really important is how they captured hearts. Children would be mesmerized by these mockingbirds who would spin a musical blessing upon those who would not even be able to enjoy music otherwise.
If anyone would want to rejoice by their presence, they'd be encouraged to tip. This might make them sound as if they were not such a mockingbird extraordinaire. It is true, it is a profession. What kind of grown up would truly be able to act and feel this way from the bottom of their hearts after strolling around a bit? It was a tough job, and poorly paid too. Such strong hearts, they had.
