Hey, sorry it's been a couple weeks since I've posted. But I'm back!
I saw this clip on Family Guy of Stewie dancing with Gene Kelly, and found a side by side comparison video of the FG version and the orignal with Jerry Mouse on YouTube (where else?). Unfortunately the person who uploaded it has disabled video embedding :( so I'm just going to have to try to convince you to click this link!
With barely any searching you can also find the full Jerry Mouse version and the full FG version.
I have to say, for Family Guy when I saw this on TV I was impressed. It's amazing how just rotoscoping the original animation, even crudely, there is so much more texture to Stewie's animation! I mean for one thing they had to draw him in poses and angles from which they never usually draw him, but it's also great to see even a hint of squash and stretch that carried over from Jerry. Don't get me wrong, I will never tout Family Guy as an example of great animation, that's not why they make it anyway. But it's an entertaining little idea, and I thought it'd be cool to post video---er, link--that shows the original too. The original was from Anchor's Aweigh.
