I think it was just a case of not realizing that these had been altered for the single. Essentially, if you're not paying too close attention, you won't notice anything drastically different on either "B'wana..." or "Flat Baroque", and both were b-sides and not the main focus of the 45 release.
Which would make sense ordinarily, but wasn’t this compilation assembled with Richard’s involvement? He was involved in its promotion from what I remember (or was that just the Christmas DVD?). He would have known surely.
