"Classic" Sun Ra

What an interesting idea: keeping in mind the title, Smithsonian Collection of Classic Jazz, I would nominate either "Planet Earth" from Sound of Joy, or "Enlightenment" from Jazz in Silhouette. I noticed that the Smithsonian has Monk performing a couple non-Monk pieces, so I think to give Sun Ra his due he must be allowed a standard and for that I would nominate "Somewhere Over the Rainbow" from Of Mythic Worlds.
