> If what you said was true, there would be no need for the lyrics display at karoke bars. You misunderstand what I'm claiming. That is exactly the issue I was describing - you recall the bulk but you make small mistakes and the skill is in reducing the small mistakes and being able to power through them and get back on track when they do happen. Playing instruments in a band is so much worse, it's not enough to know how the song goes, you need to be in perfect sync with other people, and any mistake is highlighted by the discord. In acting, there isn't another person saying your lines at the same time as you, and mild variation in pacing, intonation, etc from one performance to the next is not only acceptable but desirable. By analogy, you know what the Eiffel Tower looks like, you could probably sketch it accurately enough that someone else would recognize it as the Eiffel Tower, and they would probably be unable to tell you exactly what errors are in your sketch, even though you almost certainly don't know the count, size, and position of every beam.
