Need a review: Band in a book:Steve Kaufman. What did you think?

Well, I've aquired my share of mandolin books/cds/dvd's and most have been helpful but I do have a few duds in the bunch. Some I wasn't ready to make use of and others were of no use to me. I do like my 4 hour bluegrass workout from Steve and have used it a good bit but with so much "out there" I would like to get some opinions of his Band in a book product. Specifically The "Bluegrass vocals" edition.

Thanks, Mandodan 1960

I guess I need to review it myself. I've ordered it and will post a review soon. Mandodan1960
