My philosophy is to offer infotainment, I try to know everything there is to know about Vincent Van Gogh( my wife can't believe I still buy more books...), but I also spice it up with fun facts and anecdotal information about his life.
Judging form my reviews you can tell that people loved it for the knowledge part but also the enthusiasm I bring to the stage.
When you have kids; I tend to get them engaged too.
