Jackie Kennedy tightly controlled all aspects of that funeral....It was the ultimate Hollywood production, the final curtain for Camelot.....Then, she married Onassis..
Oddly enough, I can't find a list of speakers for the Kennedy funeral. It was a mass, so perhaps there were fewer speakers. It's hard to determine, from the articles I see, who spoke at the mass and who just "issued statements" or the like. My impression of the funeral is that Jackie did indeed want it tightly staged for maximum dramatic impact... too many speakers would detract from that, I suspect. It doesn't look like there were too many, that's for sure...
