Hey there!

I'm a big Disney buff and I have a thing for their film music. But unfortunately some music was never officially released or is out of print since a long time :(
Perhaps some of you can help me to get my hands on any of the following soundtracks... it really doesn't matter if it's an official release, promo stuff, a bootleg, a recording session or enhanced DVD/Blu-ray rip.
I will appreciate your help. Thanks in advance!!!
