That still sounds like a mischaracterization to me. Based on what
Danny said:
"So the pre big mix studio sessions were effectively all the pre big studio runs of what we were doing at home in the little studio. You'd do a little mixdown to DAT for your records so when you got to the big studio you could play it, if someone said "what are you thinking?" But before you set up all the machines and fired it at them you could play them that if they wandered in. And those DATs and subsequent notes those DAT created I reran a load of the sections that we had created, and I reran them exactly as we had done them. And I record all the notes, the effects, the levels and everything. If I didn't have a certain section as the DAT had corrupted or whatever I reran them again and cut and pasted between the various versions. The pre-big studio versions is exactly what it says; it's the versions that were done at home before the multi thousand pound machines were allowed to do the final mix."
it sounds like he just recreated the DAT mixdowns from their sessions at their home studios. Maybe I'm reading that wrong?
