There were also some in those same set of PSAs written by Irving Caesar, who wrote "Tea for Two" and lots of other pop songs. I've seen a song book called "Songs of Friendship" which includes "Thomas Jefferski", about how Thomas Jefferson could have had a different name depending on where he came from. There's another one about how God is called by different names in different cultures but it's the same God.

The one I remember but can't find lyrics for went something like

I may not know a lot of things
But one thing I can say
Both native born and foreign born
Have made our country great.

I don't know if this is Irving Caesar or not, I always thought "The Brown Cow" was, but apparently not.
