YouTube Disney Gold: Voices behind the Characters

I've come across some more of that YouTube Disney Gold. This from the Disney Family Album that must have been taped off the Disney Channel years ago. This one is the "Voices behind the Characters" and is really good. The guy that posted it is Darthkoon and he put it up in 4 parts. Part 1 starts out with Hal Smith giving his Goofy as Jacob Marley in a Christmas Carol voice. Then we get to see the transition of the voice of Mickey from Walt down to Jimmy McDonald. It was also very cool to see Alan Young as the voice of Donald's uncle, Scrooge McDuck.
Part 2 has Kathryn Beaumont talking about her work in both Alice in Wonderland and Peter Pan. Part 3 Has a great insight into the casting of Phil Harris as one of my favorite Disney Character, Baloo. He shaped that roll into his own choosing which worked to the benefit of all. In Part 4, John Byner and John Hurt talk about the Black Cauldron. john Byner was a great comic and voice actor from the 70's and 80's and John Hurt of Alien busting out of his chest at lunch fame did some great work on an overlooked Disney cartoon.
