Why are they called Duran Duran? A guide to band name etymologies

First of all, I want to thank [~knuten]: his lists gave me the inspiration for this one. Second, this list is just a collection of infos with no claim of objectivity: several etymologies are a mere personal speculation and cannot be verified. The list is constantly under construction, so please feel free to contact me for corrections and/or suggestions. Or just ask me a question, I'll do my best to find an exhaustive answer.
