I hadn't actually checked that linked page too carefully. The extra line of music looks to me like it's the first line from a different version, possibly some kind of transcription error since I think all the Bronson versions are on that site somewhere. Also the midi version is accompanied by a horribly inappropriate drone, so I think there are technical problems with the site. However, I also learned the version from 'Crystal Spring' many years ago, and - if you cut out the extra line - what's on the website seems very similar to me.
