Lady Sings the Blues is only a movie.
 The blues scale is often used in popular songs like Harold Arlen's "Blues in the Night", blues ballads like "Since I Fell for You" and "Please Send Me Someone to Love", and even in orchestral works such as George Gershwin's "Rhapsody in Blue" and "Concerto in F"
During the blues revival of the 1960s and 1970s, acoustic blues artist Taj Mahal and Texas bluesman Lightnin' Hopkins wrote and performed music that figured prominently in the critically acclaimed film Sounder (1972)
