Another great set you can get are the Tex Avery cartoons on VHS. You can get those unedited, including all the explosions causing black-face and all that. I have 4 videos of his great cartoons. It has everything from Screwy Squirrel, Droopy, Spike, and that Confederate Wolf that always whistled that funny dixie song. "Real cool maaaan."
Luckily I have a copy of Song of the South that I got in London about 10 years ago. I need to get that thing transferred to DVD so I can keep a good copy of it. I remember seeing that when I was a child (I'm 27 now). I think it's a great show and a wonderful story.
They all have the maid that beats Thomas, Jerry's uncle that plays the guitar and sings Froggy Went a Courtin', and a ton of other great clips.
There is a complete Tex Avery DVD set but it is only available from France. I don't know if the French subtitles are forced on or if you can turn them off (you would also need an R2 or Region Free, PAL capable DVD player; I have one but have held off on this DVD set).
This shows that Disney's suppression of this film is because of protests in America; they seem to stand behind the film as a corporation in other countries where it does not draw any outrage.
Now that DVD permits any nation's media to be viewed in America (region blocking and PAL/NTSC are really such minute matters), I don't see Disney Corp. ever permitting Song Of The South to be issued again. And for those who say they don't like the scenes of happy singing slaves, this film takes place AFTER the civil war.
