The name "Moody Blues" came about because band founder
Michael Pinder was
trying to get a sponsorship from a brewery named Mitchells and Butlers,
and thought if he came up with a name with the same initials it might
sway the brewery (it didn't). He picked "Moody" because one of his
favorite songs was
Duke Ellington's "Mood Indigo" and "Blues" because he was a
fan of blues music.
