"The Grunt" is a funk instrumental recorded in 1970 by James Brown's band The J.B.'s. It was released as a two-part single on King. It was one of only two instrumental singles recorded by the original J.B.'s lineup with Bootsy and Catfish Collins. Large parts of "The Grunt"'s melody and arrangement are borrowed, uncredited, from The Isley Brothers' song "Keep on Doin'", which was released earlier in the same year. Part 1 of "The Grunt" was included on The J.B.'s' 1972 album Food for Thought.
