200 People Singing Happy 40th Birthday Dungeons & Dragons

D&D turned 40 this year. To honor that, at PAX East 2014 (in Boston), I was part of a panel called "Why D&D Is Still Awesome: A 40th Anniversary Dungeons & Dragons Tribute."

But that didn't seem enough. I tried (and failed) to make a giant 40-sided die birthday cake. Instead, I lead the 200+ person crowd in a rousing "Happy Birthday to Dungeons & Dragons" singalong.

With David Ewalt, author of Of Dice and Men: The Story of Dungeons & Dragons and The People Who Play It and and Jon Peterson, author of Playing at the World: A History of Simulating Wars, People and Fantastic Adventures, from Chess to Role-Playing Games.
