Three Of A Kind- Sort Of...

Q: The Norman Lear sitcom 'All In The Family' theme song, the early 70s Stan Freberg written & directed Ann Miller tap-dancing 'Great American Soups' ad, and the opening theme song to 'Family Guy, what do they have in common?

(and the 'Family Guy' theme is presented backward to avoid copyright issues)<
