It became their first hit after being released as a single in September 1972, topping the US R&B chart and peaking at number 3 on the US Billboard Hot 100. “If You Don’t Know Me by Now” was originally written for Labelle (a trio led by Patti LaBelle) but they never recorded it.

In addition to the single release, the track was included on their debut album I Miss You. The song “If You Don’t Know Me By Now” was chosen as one of the “Songs of the Century” by the Recording Industry Association of America (RIAA).
