The title is an obvious take off on a well-known "Jeopardy!" category, as this show is comprised of four distinctly different sets. The first set might be subtitled "Harmonic Convergence" due to the fact that every song features wonderful harmonies. The second set features some new things, while the third is about communication. The fourth and final set has a bit of a ska influence; add them all together and you indeed have a Potent Potpourri.
