Just ahead - two islands - squeezed into one Geo Quiz.

The two islands we want to ask you about today ... don't quite qualify for the top ten largest islands in the world.

They actually come in at 17th and 20th. The island of Ireland lies near 53 degrees north in the North Atlantic.

Cuba's main island is located in the Caribbean at about 24 degrees north.

So what's the distance between these islands? And for extra credit, which one is bigger?

Musically speaking, these two islands seem thousands of miles apart, but we'll tell you about some musicians who're bridging that gap in today's global hit.

For now -- puzzle on the distance between Havana and Dublin.
