As the booklet says: It must be borne in mind at all times that Hip is not just a language but an attitude-indeed, a whole culture in itself". And this being from 1959 could now be considered classic Hip? Languages do evolve, and ts fun to think of this as endearing as classic Greek or Latin.
Posting it here for myself. For the time instead of bushing up on my Shakespeare, want to brush up on classic Hip.
