The name "C Moon" was inspired by lyrics in the song "Wooly Bully" by Sam the Sham and the Pharaohs. McCartney said, "There's a line in [Wooly Bully] that says, 'Let's not be L7.' Well, L7, it was explained at the time, means a square—put L and 7 together and you get a square... So I thought of the idea of putting a C and a moon together (a half-moon) to get the opposite of a square. So 'C Moon' means cool, in other words."-Wiki
