Ah, just want to say that Nick Drake's social class, and however subtly anyone may wish to grade it, has nothing to do with his power as a musician, for me.
An interesting point was raised earlier about trying to copy (or learning, should I say?) ND's guitar style. Like trying to play Nic Jones, it rarely works (never, for me, I should say, but I still have a go).
The guy was unique - yes, there were Jansch, Graham, Dave Evans, and all the other great players of that time ... and others, who we heard once: maybe when they woke up on our kitchen floor, picked up a guitar, astonished all us space cadets, and then vanished ... on a 63 'bus.
And for me, there is real beauty in much of Nick Drake's work, a rare enough quality.
