It became their first hit after being released as a single in 1972, topping the US R&B chart and peaking at number 3 on the US Billboard Hot 100. `` If You Do n't Know Me by Now '' was originally written for Labelle ( a trio led by Patti LaBelle ) but they never recorded it. Much like the issue with `` I Miss You '' and The Dells passing on it, the song 's composers Kenny Gamble and Leon Huff gave it to Harold Melvin & the Blue Notes, which featured Teddy Pendergrass as lead vocalist. In addition to the single release, the track was included on their debut album I Miss You. Patti LaBelle later made the song as part of her concert repertoire in 1982 ; a live version appears on her 1985 album, Patti. `` If You Do n't Know Me by Now '' has since been covered by a number of other artists, most notably the English pop / soul band Simply Red, who took their version to number one on the Billboard Hot 100 in 1989. The song was chosen as one of the `` Songs of the Century '' by the RIAA.
