During the 70's & 80's I used to drink at West End Cafe on 114st & B-way Across the street from Columbia University. I even read poetry there once or twice. The West End was an old hang out of Ginsberg during the 50's.
At the time Ginsburg lived in Colorado. He would come back to NYC from time to time to do a reading. I attended some of the readings. I never cared much for Ginsburg's stuff. For all his focus on excretions and emissions and such his writing is inhuman. But he was a pretty animated guy.
