I picked up this old, scratchy record thinking I would find scans of the book later (I did find photos of the front and back cover, though). The good news is, there is no book! The bad news is, there is also no Jack Mercer...instead, we get a guy who does his best, but ends up sounding more like Jimmy Durante. I have only listened to this while transferring and cleaning it, so I haven't given it an "official" listen, but what I've heard is pretty ridiculous.
POSTSCRIPT: Check out some of the characters on the back cover! Note late Warner Bros. characters like Cool Cat and Merlin the Magic Mouse! Weird!
