Why would Disney change the voice acting?

Rating: 1/10 (17 August 2010)

I agree entirely with little-bird-2. When I was growing up, I would borrow this movie from my local library. I loved it so much. Years passed, and I ended up in a relationship with a person who actually had it on VHS! I was so excited about it, I told her we HAD to watch it that night. Well, fast forward another couple of years... I bought the special edition DVD, and I couldn't wait to watch it. Pop it in, and the first thing I noticed was the opening credits had a different singer. I was a little mad about that, but it was OK. But then the dialog started. I wasted $22.00. Everything was just too strange. The original voices were perfectly fine. If they ABSOLUTELY HAD TO change it, why couldn't they just keep the same dialog at the VERY least?
