I don't know really, but one of the first things Katzenberg did when he came in was to have them tone down the ending which would have been a bit more scary and a little graphic. Either way, I don't think people responded - they never really do to the ones like that.
Yes, you are correct abtou Oliver and Company. It has a very nice soundtrack by the likes of Billy Joel, Huey Lewis, Ruth Pointer, and Bette Midler. Bette played Georgette, the stuck-up poodle who might become a bit smitten witht the roguish Dodger, as played by Billy Joel. Also, Cheech Marin plays a Chihuahua, so that's gold right there!
