Yes, thank you, Ray, for that review.
Strangely enough, as I noted from Merv Griffin's obituary, he interviewed Welles 50 times in a nine year period, yet only an edited version of the man's last appearance is included in this box set. Because, as I believe, Welles was often given an entire hour, or most of it, there is a wealth of interview material which has still not been made generally available.
I also might add, as I have earlier, somewhere here, Griffin told the late Tom Snyder, in one of their last sessions together on TV, that he often had Welles as a guest at his home, and in a downstairs rec-room, wired for sound (and perhaps video), he recored hours and hours of their more or less intimate conversations. My memory is that Griffin claimed to have over 600 hours of unedited material from these sessions stored in a vault. He indicated that, one day, he would make these interviews available.
If so, we have a new lost Welles treasure to track down.
