As a life-long fan of musical comedy, I am especially fond of The Adventures of Marco Polo, a 1956 TV special, which was never on stage. Among the brilliant lyrics of Edward Eager are several lines that are very suitable for today's crusades for  equality.  I am presenting two of them here, which were sung by the Marco Polo character by Alfred Drake.

"Strip us both down and you'd surprise me a lot if one of us has anything the other has not".

And

"I've been studying people in crowds and in dozens, we may not all be brothers, but I think at least we're cousins."
