I have earlier versions of The Guess Who's American Woman on CD and LP.
Listened to it with a big Guess Who fan here. We both found the Audio Fidelity Surround SACD blew away the earlier editions by a wide margin.
There's an acoustic intro to American Woman on the SBM 24K Gold CD that, IMO, adds a brilliant touch to American Woman which is absent from the AF QUAD SACD. In NO way, Brian, am I intimating that the AF QUAD is lacking sonically but perhaps it was an alternate version on the GOLD which sounds extremely 'audiophile' via the Meridian Reference player. In fact, on the Gold RBCD, there's a pause between this acoustic intro and the actual American Woman track which I suspect had to be an alternate version. The Gold Guess Who disc was licensed from BMG Belgium.
Perhaps Brian, being a Guess Who junkie, you've heard this version before? It's VERY COOL!
