Yes, that's what I think. The problem of course is, what could Palmer keep and what he had to return to the record labels or publishers.

The Waxman suites are available from T&V. So are the Herrmann suites.

The British suites are usually with the publishers.

Silva certainly kept theirs. (Some avail. thru Tadlow)
So did Varese, I'd guess even if only as copies.

But where is the Rozsa (Polydor/Decca) material and some the Gerhard suites.
