Shameless publicity whore that I am, most of my piano & blues harp videos contain brief "commercials" at the end to advertise the two books I've written: "Dialogue with a Christian Proselytizer" (which I discuss on my www.youtube.com/ToddAllenGates channel) and "Hunting, Gathering, & Videogames" (which I discuss on my www.youtube.com/ToddAllenGates2 channel).
