. The tone is also different - not as bright on the strings version.

The "double note" phenomenon is a digital mastering error, originated by EMI UK in the 1990s on the CD version of the double album "The Original Chart Hits 1960 - 1980", but not on the vinyl version of that release (which I also have). The error has been replicated on some other EMI and third party releases, presumably by means of cloning from the first CD to feature it.
Here's the way it appears in my record collection (from the database):

It's interesting that the CD version of "Wonderful Life/Aladdin" does not have the glitch. Presumably, the whole archive master tapes of the two LPs were used to create separate digital re-masters, ignoring other digital masters already available for some of the tracks.
The correct version has the five-note introductory phrase, the glitched recording appears to have six.
