Sundodger,
The Japanese mini LP stereo one that you got has the best version of the original stereo mix, IMO. You can find better sound — at times, vastly better sound — on the old, out of print
Little Games Sessions And More 2-CD set:
http://www.amazon.com/dp/B000008MIQ/?tag=imwan-20But that's because Ron Furmanek did a remix from the original multitracks, and like most of his work from that era it bears little resemblance to the original mix. It's audibly superior, but not what The Yardbirds or Mickie Most intended. It also includes a bunch of outtakes from the sessions. So it's worth having, but as an addition, not a replacement. (Once the Sundazed mono version comes out, I'll have
three versions of Little Games in my collection. I don't even have that many versions for Beatles albums!
