Notable as the most successful protest song to become a pop hit, earning compliments from contemporary protester John Lennon, "War" became Edwin Starr's signature song. Rather than hindering his career (as it might have done for the Temptations), "War" buoyed Starr's career, and he adopted the image of an outspoken liberal orator for many of his other early-1970s releases, including the similarly themed "Stop the War Now" from 1971. It and another 1971 single, "Funky Music Sho' 'Nuff Turns Me On", continued Starr's string of Whitfield-produced psychedelic soul hits. After 1971, Starr's career began to falter, and, citing Motown's reliance on formulas, he departed the label in the mid-1970s.
