LA News Crew Interviewing Groucho and Jack Benny Arriving @ Hollywood Bowl Concert

Has anyone ever seen a clip of a local LA news crew interviewing various celebrities as they arrived at the Beatles Hollywood Bowl show, including Groucho Marx and Jack Benny, to name a few? I remember Groucho saying that "the Beatles were pretty great", and that he was also "here for the free booze". Has anyone seen it, or know where on earth I can get it? My good buddy Dave Meile in Lincoln, Nebraska, who was a HUGE Beatles fan, had it on BETA or VHS years ago. Dave passed away a couple years ago, and all his stuff was given away to all his friends back home. I moved from Lincoln many years ago. I've SEEN the clip, but not since then.
Thanks!
