No one could write musical earwigs like the Sherman Brothers for Walt Disney; think of “It’s A Small World” written for the Kodak exhibition at the 1964-1965 New York Worlds Fair. Here’s another; written for the General Electric Carousel of Progress at the same fair.
After the fair closed, the exhibit was moved to Disneyland and then on to Disney World’s Magic Kingdom so generations of tourists could go out into the world and never get this song out of their head. (After all, our family saw the show in 1964, and I still remember it.) You’re welcome.
