It does have a UPC rather than an EAN, however there are differences between this and the box version. The box version says US on it and on the CD. This CDI Jewel case has England on the box and Germany on the CD. I think we are safe to move the item into CDI [EU] category.
I did happen to find instances of "US versions" of CDI programs sold in Europe, that have a label saying as much on the outer shrinkwrap. It is possible that the Children's Musical Theater is one of these types of releases. We need more information on it.
In any case, we still need to know what this CDI jewel case is. I'm sure it has an actual name.
