Litkicks is mentioned...
in the introduction of one of the later interviews, I can't remember which, I don't have it with me... but yeah, It mentions AG being shown Levi Ashers' Litkicks site!!!
I love the book. Read it at the bookstore for months until I ran into a copy at a remaindered bookstore at 75% off of $3.99...good deal.
Yes, the interview you mentioned is a hoot! I like the one after the death of Ezra Pound as well. Ginsberg kind of comes off as a lecher in the older pieces, but for me that's part of his charm.
