This also brings to memory the Disney Sing-Along Songs series released on VHS (later on DVD) that ran from 1986 through 2006. It incorporated the "bouncing ball" that helped us sing along. The very first volume was titled "Zip-a-Dee-Doo-Dah" which featured the song and clip from Song of the South. In fact, that initial release happened to promote the 40th Anniversary re-release of the movie in theaters. That release brought in $37,459,346 ($87,914,438 in today's dollars) in the box office. I believe it was only re-released domestically.
For comparison, PatF only grossed $104,400,899 ($125,699,042 in today's dollars). This, of course, doesn't take in account pre-1986 earning for SotS which in today's dollars is over $1B. Worldwide, PatF pulled in $324,576,765 in today's dollars.
Note: All numbers above are theatrical release only and don't account for video sales which I'm not sure will be readily available since SotS was never released in the US on video.
This brings back a lot of memories!
