Would it be anything to do with the words "revised version", tinners? If the other recording is an "original version", then that might explain it....
Ron, either I'm going blind or you're seeing things. Where does it say 'revised version'??
Just follow the link you offered, t_i_n. It's a bit equivocal. It mentions the revised version, but I don't think it actually says the recording is of the revised version. Also, I would have thought the EMI recording would probably also have been of the revised version.
