Somewhere out there...
Doesn't Little Dorrit sound like the name of a mouse? He and his Russian family decide to move to America and some singing and dancing ensue... and then they become cowboys. Ohh wait... that's Fievel Mousekewitz. I'm assuming Dickens wasn't involved in the animation industry in the early 90's.
Oh well. Although singing mice would've been MUCH more entertaining... I guess I'll just read Little Dorrit by Charles Dickens instead
