Brian Wilson's "F" in his high school music class has been upgraded nearly 60 years later to an "A." Back in 1959, the Beach Boys leader submitted the music to what became the band's first single, 1961's "Surfin'," which originally earned Wilson an "F." Wilson posted on Twitter: "Brian’s high school music teacher Fred Morgan: 'Brian wrote a composition for me and it turned out to be 'Surfin'. That composition got an F, but it made a million dollars.' Brian’s failing grade has now been changed to an 'A' on this assignment by (Hawthorne High School's principal) Dr. Landesfeind!"
