Ginsberg = one hell of a poet and Cannabis activist.
For the youngin's among us, here is the much imitated (i.e. Gieco commerical) never duplicated early music vid Subterannean Homesick Blues by Bob Dylan
Ginsberg is the dude standing to the left of Dylan during the vid - then he walks cross screen at the end (homage by Dylan to his peer/mentor)
Update;
Drifting just a little off topic, but hopefully still in range
Check out the homage from Weird Al to Dylan in the music vid below.
It's accurate right down to the fake Ginsberg.
For those that don't get the joke right off, Dylan has a rep for mumbling and/or making no sense sometimes.
Weird Al's lyrics may seem like this at first observation, but in truth the entire song is a Palendrome (the word or phrase reads the same back to front as front to back)
