We've been on hiatus here at The Daily Beat while traveling in Arizona and California, making a conscious effort to leave the everyday life behind and enjoy "vacation." Nevertheless, Jack Kerouac followed me on my travels as I ran into this in a Flagstaff used bookstore and, not owning it, had to fork over the $9.95 asking price.
Conversations with Jack Kerouac was edited by Kevin J. Hayes and published in 2005 by University Press of Mississippi. Hayes was (is?) a professor of English at the University of Central Oklahoma, and in this book he pulls together such various pieces as Mike Wallace's 1958 interview with Jack, a 1958 San Francisco Examiner interview, Al Aronowitz's 1959 piece, "St. Jack (Annotated by Jack Kerouac)", Stan Isaac's "Playing 'Baseball' with Jack Kerouac" from Newsday in 1961, the Ted Berrigan 1967 Paris Review interview, and several others (10 in all).
I haven't read it yet, and most if not all of these pieces will be familiar to the loyal Kerouacian. I don't think I've read either of the Newsday interviews by Val Duncan (1959 and 1964). In addition, it contains an interesting introduction by the editor which you won't find anywhere else. The Kerouac included Kerouac chronology is standard fare.
Don't pay $9.95 (plus tax) for it unless you want to support your local used bookstore: I see a used copy on Amazon for $2.57.
