I was fortunate enough to have bought this book from Mr. Bishop personally in the late 1970's or early '80s, after seeing him perform. I seem to remember him autographing it for me, but the book contains no autograph. Either I had asked him, but there was no pen available or he used invisible ink (or I was............never mind!).
*I remember now. As I had several copies of the book, I inadvertently lent or gave the autographed copy away to a student without checking. Careless maybe, but I know I wasn't trippin'.
It is said that Woody Shaw practiced out of this book, and maybe he did. But it is well documented that he played the way he did (using lines comprised of 4ths, not common on trumpet), long before this book appeared in 1976.
