Because I'm feeling generous today, I leave you with Part 1 (of 12) of The Peter Green Story. If you don't know who Peter Green is, then you should be beaten with a stick*. Green, like Syd Barrett, was an awesomely gifted talent but he couldn't quite handle the scene and burned out too quickly. So, edjermocate yourselves and watch all 12 episodes.
*this holds true for Peter Green the historian as well. His work on Alexander The Great is without peer.
