including one of Jack with Jimmy Stewart and other pallbearers for Gary Cooper. They're standing waiting on a sidewalk, by a hearse, and the background is an almost industrial-looking street-- I guess it's the old-style "wig-wag" railroad crossing signals that give it that feel. My wild guess is that it might be at a church on Santa Monica Blvd. (which had a Pacific Electric line running in it.)
I digress...

Got one right though-- it was at Church of the Good Shepard, Bedford at Santa Monica Blvd. (Beverly Hills)
