Check out this 1956 special on the 50th anniversary of Beverly Hills:



I only learned about this show about a month ago and now here it is on Youtube. You get to see Groucho, Harpo, and Chico but not together. Harold Lloyd and family shows up at about 1:02:00. Plenty of shots of famous families with their unpolished kids.

It's amusing seeing Chico pop up repeatedly through the festivities, and interesting that everybody pronounces the name as "Cheek-o". One assumes he gave up correcting people long before this.

Correction...Groucho and Chico DO appear in a short bit together, at 1:11:00.
