it's this video and I think it's rather nicely done (don't hate me
for the music :P):

While it sounds like you may have found something that gets the job
done, I got better quality (to my ears) than mplayer or VLC like this:
$ ffmpeg -i careless-whisper-piano-orig.mp4 -an -b:v 1022k -vf
"setpts=(1/0.25)*PTS" careless-whisper-piano-tutorial.mp4
$ ffmpeg -i careless-whisper-piano-orig.mp4
careless-whisper-piano-tutorial.wav
$ rubberband -t4 careless-whisper-piano-tutorial.wav
careless-whisper-piano-tutorial-stretched.wav
$ ffmpeg -i careless-whisper-piano-tutorial.mp4 -i
careless-whisper-piano-tutorial-stretched.wav -c:v copy
careless-whisper-piano-tutorial-stretched.mp4
It took a while (probably 20 minutes on my underpowered laptop) but I
think this is the method I'll be using the next time I want to learn
a part. Not really a fan of this particular song, but stretched out
4:1 it sounds kind of mellow and what artifacts I hear just make it a
little bit trippy, while making any Richard-Clayderman-esque
parallel-6th abuse and other easy-listening cliches in this
arrangement less noticeable. So, that's an improvement.

Thanks a lot Rob.
I finally came around to try this method and it sounds indeed better
than the on-the-fly methods in VLC and so on.
I find it funny that, according to Wikipedia, George Michael himself
doesn't particularly like the song (at least the lyrics). I'm not a
George Michael fan nor do I particularly like easy listening music,
quite on the contrary, but it's a nice enough song and I figured it's
not too hard to learn. Once I know how to play it I'll play
with it and interpret it anyway. Let's see how that will turn out :)
Regards,
Philipp
