I just stumbled upon a bit of an oddity today - as part of the Bruce Herschensohn Collection at the Pepperdine University archives, there exists an archived and digitzed letter dated March 1964 addressed from
Hans Conzelmann on behalf of Dehace Music Production GmbH (Conzelmann and Delle Haensch's production company) addressed to
William Loose at Capitol Records.
From what I've gathered, the letter is related to the production of director Herschensohn's documentary "John F. Kennedy: Years of Ligthining, Day of Drums" for which the director himself was actually the composer - his compositions seems to have been sent off to Capitol Custom, orchestrated and scored by Loose (and Jack Cookerly(?)) and then shipped to Conzelmann and Haensch in München for recording.
It's honestly a pretty mundane letter accompanying an invoice charging for use of studio musicians, equipment, etc., but is a curious connection between Loose who at this time would have been knee-deep in Capitol Hi-"Q" reels and Conzelmann and Haensch who would perhaps soon be starting off with the earliest of their work for Selected Sound. I'm sure 'cross-pollination' like this was perhaps commonplace, but it's odd to see something as explicit from these otherwise fairly mysterious workhorses on their separate ends of the world.
