Got it... well if you have the SQ LP release and the CD already I don't know why you'd want the tape versions, and the 1/2 speed master...well, you'd probably be paying too much for a copy of Annie! :yikes Just kidding, just not a fan. I'd say since the CD was encoded then it is a very fair bet that at least the two tape versions are also encoded, but that's just a semi-educated guess. Would they even be reproducible back to quad from a stereo cassette? John
