Renowned bassist Bob Babbitt died Monday after a lengthy battle with brain cancer. He was 74. Born Robert Kreinar, Babbitt is a legend in the music industry for having been one of the Funk Brothers collective that backed dozens of musicians on the Motown Records label in the 1960s and ’70s. His playing can be heard on some of the biggest hits of the era, including Del Shannon’s “Little Town Flirt,” Gladys Knight’s “Midnight Train to Georgia,” Stevie Wonder’s “Signed, Sealed, Delivered,” the Temptations’ “Ball of Confusion,” “Inner City Blues” by Marvin Gaye, Edwin Starr’s “War,” “Rubberband Man” by the Spinners, and Dennis Coffey’s instrumental hit “Scorpio.”  Babbitt is survived by his wife, Ann, two daughters, and one son.
