You may be onto something there. Pathetic, but I would line up for both of those as I love SACD surround! ATD and WYWH are sublime on SACD, imho. All I know is that if the surround mixes have been nixed, then we, the fans, end up losing (again). Having said that, I think it's wonderful that they've decided to release so much of the earlier stuff after dismissing it for so very long...
Guthrie, Jackson, whomever, let's hear those 5.1 mixes please!!!
