Southern Nights is a 1975 R&B concept album by Allen Toussaint. Seminal to the development of New Orleans R&B, Toussaint incorporated into the album elements of funk and soul music, while, according to AllMusic, suggesting neo-psychedelia. Two singles were released in support of the album, "Country John" backed with "When the Party's Over" and "Southern Nights"—Toussaint's signature song—backed with "Out of the City". Although neither single charted for Toussaint, "Southern Nights" as later covered by Glen Campbell in 1977 reached number one in Billboard's country, pop and adult contemporary charts. Released in May 1975 by Reprise Records, the album has been subsequently reissued multiple times on both LP and CD.
