There are a few songs whose lyrics were changed by the composer after the initial version was released, resulting in the existence of two (or more) versions of the lyrics. Sometimes it's possible to guess the reason for this, other times one is just left to wonder why. In the SMiLE thread I pondered the fact that Good Vibrations comes in two versions. First verse, single version: "Brian Wilson Presents SMiLE" album version: What was going on there? Nothing wrong with the modified version, but why change the original? Any other examples we can identify?
