Look at some of the comments to find out more info on what is included.
The footage that you had seen previously was from Main Street, and part of that is featured in the Steve Martin Donald Duck movie in DL's Opera House. I don't recall off hand if that footage is on this DVD set, as only the previously unseen footage stands out in my mind.
I love that DVD. Got it for my birthday last year. I would love to just sit in a theater and watch all that old footage straight through.
Our revels now are ended. These our actors, As I foretold you, were all spirits and Are melted into air, into thin air: And, like the baseless fabric of this vision, The cloud-capp'd towers, the gorgeous palaces, The solemn temples, the great globe itself, Yea, all which it inherit, shall dissolve And, like this insubstantial pageant faded, Leave not a rack behind. We are such stuff As dreams are made on, and our little life Is rounded with a sleep. mycroft16 on Twitter
