There is someone on ioffer that has been selling a restored version of the scene (Google: ioffer, pastoral, fantasia). It may be somehow related to Andrea Ippoliti's restoration (which was a hybrid of "Walt Disney's Wonderful World of Color" and the Fantasia DVD. It is posted on YouTube. http://classiccartoons.blogspot.com/2008/07/return-of-sunflower.html
Has anyone seen the DVD version or any fan restored version?
