Note that Funny Factory with Huey, Dewey & Louie contains four Donald Duck shorts that have never been released on DVD before. So if you want them now, I think it's a good purchase. Or you can wait for them to come out on a Treasures set - your choice!
And even though no one from Walt Disney Home Video is actually here, I would love to make a suggestion about what song came to mind when I heard of this/these release(s).
That song - "Laughing Place," I think would make a good audio to put over the disc's menus.
Actually I was just thinking of them when I was in the shower. They were in a video that I used to love when I was a kid - Kids is Kids (a compilation of cartoons with them and Uncle Donald). I still have most of it on tape (part of it was accidentally taped over). That was a very good special. Maybe part of it is on a Treasures of Huey Louie and Duey (if there has been one yet).
