So I just picked up a UA blue label copy of this from '73 'cause I wanted to hear the stereo version and didn't feel like paying $30 for the Classic . Well, I get it and it has the stereo cat# but on the back cover it has the infamous "Electronically Re-Recorded To Simulate Stereo" . Why would they need to do this if a true stereo master exists, which according to the Classic blurb for the lp does? Maybe Steve or Joe Harley can address this? Thanks.
