The day after I read the fine article on Clyde's career by Chris Berry and Dave Price, I stumbled across an entry in the National Archives. It is part of a subject index of newsreel films made by Universal from 1929-1967. It was filmed on April 14, 1935, and has the subject index "Clyde Beatty and His 'Cats' Raring to Go" while the personality is King, Allen. (Who worked cats and bears.)
It says that not all the films still exist, but if anyone wants a scan of this entry, email me at reinertg@hushmail.com The record entry at the archives website is https://catalog.archives.gov/id/102702382
