That version is only contained in all the original EMI releases (CDP 7 46033 2, both red and silver CD pressings) and even on the 1992 reissue from Parlophone (also included in the green GH I&II box).
The Digital Master Series from 1994 and all the newer releases DO NOT contain the original single mix - they have the regular album version instead.

The Save Me 7" was released 6 months before The Game. As a result,
the single has the same performance but a slightly different mix compared
to the final version that appeared on the album. You can really hear the
differences on Freddie's vocals, which are phased. The cymbals are buried
in the mix and the guitar part around 1:30 is mixed differently as well.
