Allen Toussaint (; January 14, 1938 - November 10, 2015) was an American musician, songwriter, arranger and record producer, who was an influential figure in New Orleans R&B from the 1950s to the end of the century, described as "one of popular music's great backroom figures." Many musicians recorded Toussaint's compositions, including "Java", "Mother-in-Law", "I Like It
The youngest of three children, Toussaint was born in 1938 in New Orleans and grew up in a shotgun house in the Gert Town neighborhood, where his mother, Naomi Neville (whose name he later adopted pseudonymously for some of his works), welcomed and fed all manner of musicians as they practiced and recorded with her son. His father, Clarence, worked on the railway and played trumpet. Allen Toussaint learned piano as a child and took informal music lessons from an elderly neighbor, Ernest Pinn. In his teens he played in a band, the Flamingos, with the guitarist Snooks Eaglin, before dropping out of school. A significant early influence on Toussaint was the syncopated "second-line" piano style of Professor Longhair. After a lucky break at age 17, in which he stood in for Huey "Piano" Smith at a performance with Earl King's band in Prichard, Alabama, Toussaint was introduced to a group of local musicians led by Dave Bartholomew, who performed regularly at the Dew Drop Inn, a nightclub on Lasalle Street in Uptown New Orleans. His first recording was in 1957 as a stand-in for Fats Domino on Domino's record "I Want You to Know", on which Toussaint played piano and Domino overdubbed his vocals. His first success as a producer also came in 1957 with Lee Allen's "Walking with Mr. Lee". He began performing regularly in Bartholomew's band, and he recorded with Fats Domino, Smiley Lewis, Lee Allen and other leading New Orleans performers. After being spotted as a sideman by the A&R man Danny Kessler, he initially recorded for RCA Records as Al Tousan. In early 1958 he recorded an album of instrumentals, The Wild Sound of New Orleans, with a band including Alvin "Red" Tyler (baritone sax), either Nat Perrilliat or Lee Allen (tenor sax), either Justin Adams or Roy Montrell (guitar), Frank Fields (bass), and Charles "Hungry" Williams (drums). The recordings included Toussaint and Tyler's composition "Java", which first charted for Floyd Cramer in 1962 and became a number 4 pop hit for Al Hirt (also on RCA) in 1964. Toussaint also recorded and co-wrote songs with Allen Orange in the early 1960s.

The Famous Flames were an American rhythm and blues vocal group founded in Toccoa, Georgia, in 1953 by Bobby Byrd. James Brown began his career as a member of the Famous Flames, emerging as the lead singer by the time of their first professional recording, "Please, Please, Please", in 1956. On hit songs such as "Try Me", "Bewildered", "Think", "I Don't Mind", and "I'll Go Crazy", the Flames' smooth backing harmonies contrasted strikingly with Brown's raw, impassioned delivery, and their synchronized dance steps were a prominent feature of their live shows. Altogether, they performed on 12 songs that reached the Billboard R&B and pop charts, in addition to being featured on numerous albums, including the groundbreaking Live at the Apollo.
In 1964, James Brown and Bobby Byrd formed their own production company, Fair Deal, in an attempt to promote their recordings to a crossover audience. As a result, Brown signed a contract with Smash Records, a subsidiary of Mercury to distribute the records. After the release of "Out of Sight", however, King Records stopped Brown from releasing any more recordings since he had not obtained the label's consent. This resulted in Brown not releasing any recordings for a year. In 1965, King released Brown's "Papa's Got a Brand New Bag", which became Brown's first number 1 as a solo artist on the R&B charts, as well reaching the top 10 of the Billboard Hot 100. The song also provided one of the first glimpses into a new sound cultivated by Brown and the James Brown Band that would later be labeled as funk. The group performed in Hollywood movies such as Ski Party and appearing twice on The Ed Sullivan Show in 1966 (where The Flames were uncredited). The group also began to perform overseas and became a major attraction. About their success outside America, Famous Flame Bobby Bennett said, in an 2012 interview with the Cleveland Plain Dealer; "We were drawing crowds everywhere we went," says Bennett. "Not just in America. We'd go to London or Paris and we couldn't even leave the hotel to go sightseeing because we were getting mobbed by people." Brown's solo aspirations led to the further dissension in the group, who felt they weren't being compensated properly. Lloyd Stallworth left the Flames shortly after the group's first appearance on The Ed Sullivan Show in early 1966, leaving Brown, Byrd, and Bennett. Dissension continued to grow throughout 1966 and 1967, and in 1968 the rest of the members of the Famous Flames decided to go on with their own separate careers, and the group quietly disappeared. In 1968, King released the group's Live at the Apollo, Volume II but edited out the Famous Flames' introduction, since the group had left Brown by then. The 2003 CD re-release of the album corrected that by restoring The Famous Flames' name credit.
