Versions of "Betty Jean"

The following discussion on the various versions of "Betty Jean" took place in email first. It is worth repeating here:
Rick Bergemann asked:

The identical version of "Betty Jean" is included in the "Anthology" and "Rock´n´Roll Rarities" cd´s, and that version differs from the version included on the 1987 cd re-issue of "Rockin´ At The Hops". I asked about this discrepancy long ago and was told that the "Rarites" version was an alternate take and that the "Anthology" version was the originally released version. Obviously that answer was incorrect, because those two versions are the same. And the fact that neither "Rarities" nor "Anthology" lists that particular version as an alternate take (while specifically noting all other alternate takes) leads me to believe that their version is actually the original. Therefore I have strong suspicion that the odd version (included in the "Hops" re-issue) is actually the alternate take. I know that this site is mainly for people who collect vintage vinyl and bootlegs and such and probably won´t think twice about what´s included on recently mass produced cd´s. But if someone of knowledge has a copy of the aforementioned cd´s, can you please listen to the versions of "Betty Jean" and explain the discrepancy clearly. Thank you.

The version on Rarities is known as the alternate version, simply because it´s the one released later. You can distinguish the two best by listening to the Little-Richard-style Oooh´s and Aaah´s both after the first verses and best at the end of the song. In the original the first verse ends with something that sounds like Whoo Ha Oh Baby, Whooo Whooo - while in the alt. version the same part sounds like Oh oh oh Baby, Oh oh oh oh Baby. The 2:25 minute alt version ends with three identical repetitions of Whoo Ha Baby I´m in love with, while the 2:30 minute original ends with Whoo Ha Baby I´m in love with - Whoo Baby I´m in love with YOU - Whoooo I´m in love with you - Whoo Baby (...fading...)
Follow up from Rick Bergemann:

Thank you for the detailed answer. You made it very easy for me to compare the two and confirm which was which. However it leads me to a second question: do you have any knowledge as to why the later version has been included on "Rarities" and "Anthology" without proper notation? "Rarities" includes demos and alt versions as well as originals, yet it does not mention "Betty Jean" as being anything else besides a "stereo remix". "Anthology" compiles only originally released versions (with a couple of entirely unreleased songs thrown in), yet this second version of "Betty Jean" has somehow been included there too. And like "Rarities", the "Anthology" liner notes also fail to note that "Betty Jean" is not the originally released version. Due to the lack of notation on either cd´s liner notes, I can only assume that MCA thought they were putting the original version of "Betty Jean" on both of those compilations.

You are probably correct. Already in 1973 someone at Chess took the wrong tape when collecting the contents for Chuck Berry´s Golden Decade Vol. 2 (Chess LP 60023). This is where the alt. version first appeared, not noted on the cover, too.
