Johnny Grant -Honorary Mayor of Hollywood

I just read in the news that Johnny Grant, the Honorary Mayor of Hollywood has died. In the obituary it mentioned that Johnny Grant played a bit part in the movie "The Babe Ruth Story" If this is true and verifiable then Johnny Grant should certainly be listed in the lengthy listing of Cast and Crew following "The Babe Ruth Story"
Maybe he is listed under another name in the credits. There are a number of 'newsboys" cast in the movie given "The Babes storied identification and rapport with newsboys and youth of all ages.
Johnny Grant had such a long storybook career of so many facets; just think what a biopic of his life would be... A living history of Hollywood and the movie culture for such a long time. It would be a treat just to cast all the larger-than-life characters of Hollywood during the reign of Johnny Grant. A real,honest-to-goodness movie,not a documentary of film clips.
