Philippé Wynne handles lead vocals, although Bobby Smith provides these two lines in the bridge following the first verse: Released as the third single from their 1973 self-titled album on Atlantic Records, "One of a Kind (Love Affair)" was the group's third consecutive Number 1 on the U.S. R&B Singles Chart, and spent four weeks at the top spot.

It also reached the Number 11 position on Billboard Pop Singles chart[2] and was certified gold by the RIAA.
