The latest issue of Rolling Stone has a very flattering review of the Disney Blu-ray, but mentions, "Unless it's hidden, the early "work in progress" version that appeared on that previous DVD set is a notable omission." Surely it must be on there somewhere....? If not, I'll have to buy back the previous set and add the first disc from it into this set. I had to do that with SLEEPING BEAUTY when I discovered the DVD and Blu editions had different commentary tracks. I should have learned from that!
