between that and "I Was Only Kidding" as my all time favorite Al song.
From what I understand (correct me if I'm wrong), Al was working with something called "Pro Tools" which (among many other things), can take out micro pauses between words so they can be compressed into a shorter time frame without making the words intelligible.
There are also a multitude of "layers" in the song (about 35-40) which cannot be recreated live. I'm sure you can tell that from the "richness" of the song... it's a veritable woven carpet of finely textured sounds.
Ultimately, the song is just too technically complex to be done live. But it is a brilliant song
