This is not a classic rag, though it seems enough like one that I'm not sure where else to put it. It was started in the beta 1.1 #1 release and last worked on in the #4 release.
Its origins lie in the time before one could purchase even a Hallicrafters 7" TV, otherwise sometimes known as Radio Days. Summers were hotter then and winters colder, and especially after the early darkness in the winter, someone my age spent hours sitting next to the radio all ears. One thing radio had in common with TV was lots of ads, and most, if not all, of these had catchy jingles set to music, and that music could start to go through your head, whether you wished it to or not. "Derring-do" represents a purgation of some of those snippets of tunes that kept going through my head long after radio became the monster it is to this day.
