For today's global hit, we're tuning into music recorded in and around Monrovia, Liberia in the 1940s.

It's all on a CD called "Songs of the African Coast, Café Music of Liberia."

The Greenwood Singers were a popular group in Liberia in western Africa the late 1940s. But if it wasn't for American ethnomusicologist Arthur Alberts, the rest of the world may never have heard them.

We spoke with Gutherie Alberts, the great nephew of Arthur Alberts.

ALBERTS: "...during the second World War my Great Uncle was in the Office of War Information and during his trips to Africa he became interested in some of the music that he was hearing on the continent. And after the war became determined to return to that region of the world and do more extensive recording trips through not only Liberia, but other countries such as Congo, Nigeria, Ghana, and such."
