Considering that The Funk Brothers comprised 13 musicians, Justman does wonders in keeping the screen time balanced between them. Clearly, some come to the fore: James Jamerson, considered the finest bass player in the world, who used one-fingered upright bass techniques on the new electric Fender Precision; Eddie "Bongo" Brown, who created spontaneous interlocking rhythms on the bongos though he couldn't read a note of music (one of the Brothers recalls seeing a nudie magazine on the stand in place of the sheet music); and guitarist Joe Messina, who had played for Charlie Parker and Miles Davis but hadn't picked up a guitar for 30 years before the Royal Oak concerts.
