Dries Buytaert had mentioned that when the Drupal developers came together at the Open Source CMS Summit he hoped they could make a video using Jeff Robbin's catchy Drupal Song.  I'm not sure the status of that video by the developers, but as a fan of Drupal I decided to beat them to the punch.

My son and I have become addicted to The Drupal Song.  In fact, when the song is playing in my house we quickly become The Drupal Boys.
