In 1966, after hearing a song about unrequited love written for The Spinners, he persuaded the writers that he should record it himself. Ruffin's recording of "What Becomes of the Brokenhearted" became a major success. It was able to peak at #7 on the "Billboard" Hot 100 and #6 on the R&amp;B Chart. It remains as his most well known song.
