This is fascinating.
Watching a comedian tackle the same early material but with 33 years experience under his belt is a good way to learn. See how much tighter it is, how much more in his own voice it feels the second time round. Even more remarkable when you consider he was doing it on Late Night in 1982 having done it a thousand times in the clubs beforehand. Second time round, he probably did a few times to a small crowd, and nothing more.
If you can cut a word and keep the joke, do it. In fact, if you can cut anything and still keep your meaning, cut it.
