b_grimmski...that really is very amazing! I found the video from Les Baxter on YouTube http://www.youtube.com/watch?v=v3TIyxa36_c . I'm always interested in the origins of some of these sampled-compiled songs and this was a great find. Thanks!
The vocal sample is from the song Moon Moods by Les Baxter & Samuel J. Hoffman (famous thereminist) from the album Music out of the Moon (1947).
Actually the whole song is a remake of the original by Les Baxter.
