I just got the new reissue of "Journey to the Centre of the Eye" in, and it DEFINITELY contains a 5.1 surround sound SACD.
The other two discs are regular audio CDs labeled "Recorded November 13, 1971 at Bessunger Turnhalle in Darmstadt, Germany"
The live audio on these two extra CDs must be from an audience bootleg because the quality is very poor, but the good news obviously is that yes, this is a 5.1 surround sound SACD that you can buy for $17 (or even less) so don't hesitate to get one!
Yep, got mine too.
