There were two different editions of this book. See below: the backcover of the first one (1) had a misprint: "Hab Gnade mit seine Seele!" that was corrected on the 2nd edition (2) "Hab Gnade mit seiner Seele!". The name of Joan Baez also went from the left to the right. Both are given out as the same edition. Thank you to Jürgen Wasser for these precisions.
