One of the SweetDuo is a David and the other is his biggest fan. That got us thinking about David duos. There aren't that many places where Davids come together. An internet search found David + David, but we have never heard of them. There is a Dr. Seuss Book called "Too Many Daves" but that really isn't a convergence of Davids. I bet you can find at least one convergence of Davids if you try.
