Pluto may have gotten all the press last week, but tomorrow marks the 46th anniversary of Neil Armstrong and Buzz Aldrin setting foot on the moon back in 1969. So in honor of National Moon Day–which, yes, is an actual unofficial holiday–we have a great tune to download about Earth’s own natural satellite.

Danny Weinkauf’s rocking tune The Moon is Made of Cheese combines lyrics about the celebrated space walk back in ’69 with the amusing belief of kids everywhere that the moon is not rock and sand, but cheese. From his most-excellent debut album, No School Today, this song from the Grammy-award-winning composer and They Might Be Giants’ bandmate may get your kids staring up into the night sky a bit more intently, trying to figure out if what he says is true.
