Nothing to add about the article or the record except to point out that there are a good many things not on the Internet, and that you often have to dip into print sources.
Aside from that, it's good news about the DVD. I really love this movie. I liked it long before I even knew who Grayson Hall was. Aside from the inexplicability of Hayley Mills and Dorothy Provine being sisters, it's a fun flick with a great cast. Anyone know what extras we might expect?
