It was a new recording. Hackett said afterwards that a lot of stuff he did for this new version wasn't used in the end.
Nevertheless, they were not in the studio at the same time.
Thanks so much. If Hackett says they didn't use a lot of what he did, that means that they nevertheless did use at least some of what he did; and so he's on the new track at least to some extent. Do I have that right?
And again, very much appreciate this information. Thanks.
