And yet the hall was insistent that Mark Evans (original bass player for AC/DC who played on most of their early classics) should be in....but the Young brothers said "NO" and his name was removed. That's right, he was originally announced as getting in, and then silently removed a few days before the ceremony with no explanation. So the whole thing seems very "case by case" and whoever can argue their case better, and the hall might have the final say, but they can also be persuaded if they want somebody's participation bad enough. (and they didn't give a rats ass about whether KISS participated or not)
But the Duran Duran comments in here are baffling to me. I always considered them to be a more shallow version of The Cure and DM. Certainly popular, but not as fundamentally influential as the first two....who did come first IIRC.
EDIT - Guess I'm wrong. According to the "years active" tag on Wiki, The Cure formed in 76, DD in 78, and DM in 80. However The Cure released their debut in 79, and was on the third album in 81 when DD and DM released their debut albums. And I don't think anyone knew who DD were until Rio, whereas DM had already begun to make a name for themselves by that point.
