It's one thing to be famous. It's another thing altogether to be legendary, or like a legend. The Monkeys were a famous band. The Beatles are legendary—for most people, they are almost mythical in their greatness.
There are a couple of ways to become legendary, but, however you get there, you have to become a legend. The first way is to be better at something than anyone else ever was. Michael Jordan, for example, is a legendary basketball player. The other way is to be known—and yet remain mysterious—for a very long time. The legendary Loch Ness Monster, for example, is very well known for a creature that (almost?) no one has ever actually seen.
