input: Sam Moore and Dave Prater's early musical backgrounds involved listening to and singing gospel music in their homes and churches, and in Dave's case, also singing gospel in the choir in his church. Dave later sang with his older brother JT Prater in the gospel group The Sensational Hummingbirds, who recorded "Lord Teach Me" in the 1950s. Sam recorded "Nitey-Nite"/"Caveman Rock" in 1954 with the doo-wop group The Majestics, and later sang with the gospel groups The Gales and The Mellonaires. Moore and Prater listed Jackie Wilson and Sam Cooke as influences on their styles, and Moore was also influenced by Little Willie John, whom he and Dave opened for often in the early 1960s.  Sam & Dave met working the gospel music circuit, and later in small clubs in Miami during amateur nights in 1961 according to Dave. They sang together one night at the King of Hearts club, and started working together immediately thereafter, developing a live act featuring gospel-inspired call-and-response. Soul singer and record producer Steve Alaimo discovered them while performing during the same show with them at the King of Hearts nightclub in Miami and signed them to Marlin Records.  After two singles in early 1962 were released on the local Marlin label owned by Miami's Henry Stone, Stone helped sign them to Roulette Records in New York City. They released six 45s from 1962-1964 (two were re-releases of Marlin recordings) with Roulette, and one single on Stone and Alaimo's Alston Label. A few of the singles received regional airplay, but did not achieve national chart success. The songs, some of which were produced by Steve Alaimo and some of which were produced by Henry Glover, were similar in many ways to R&B recordings by Sam Cooke, Jackie Wilson and Little Willie John. Prater was the lead vocalist on most of these singles, with Moore singing harmony and alternate verses.  In summer 1964, Stone introduced the duo to Atlantic Records' Jerry Wexler, who signed them to Atlantic. Wexler asked Memphis, Tennessee-based Stax Records, which Atlantic distributed nationally, to work with Sam & Dave. Wexler wanted the Southern roots and gospel style of their live performances, so the pair were loaned to Stax to record, although they remained Atlantic Records artists. According to Wexler's autobiography Rhythms & Blues, "Their live act was filled with animation, harmony and seeming goodwill. I put Sam in the sweet tradition of Sam Cooke or Solomon Burke, while Dave had an ominous Four Tops' Levi Stubbs-sounding voice, the preacher promising hellfire."

Question: Bobby Darin (born Walden Robert Cassotto; May 14, 1936 - December 20, 1973) was an American singer, songwriter, multi-instrumentalist, and actor in film and television. He performed jazz, pop, rock and roll, folk, swing, and country music. He started his career as a songwriter for Connie Francis.

Born Walden Robert Cassotto in the East Harlem neighborhood of New York City, Bobby Darin was reared by his maternal grandmother, whom he believed was his mother. Darin's birth mother, Vanina Juliette "Nina" Cassotto (born November 30, 1917), became pregnant with him in the summer of 1935 when she was 17. Presumably because of the scandalous nature of out-of-wedlock pregnancies in that era, Nina and her mother hatched a plan to pass her baby off as Nina's younger brother. Years later, when Nina finally told Darin the truth about his upbringing, she refused to reveal the identity of his biological father, and kept the secret to her death in 1983. Darin's maternal grandfather, Saverio Antonio "Big Sam Curly" Cassotto (born January 26, 1882), was of Italian descent and a would-be mobster who died in prison from pneumonia a year before Darin's birth. His maternal grandmother, Vivian Fern Walden (also born in 1882), who called herself Polly, was of English ancestry and a vaudeville singer. From his birth, Darin always believed Nina to be his older sister and Polly his mother. But in 1968, when he was 32, Nina told Darin the truth, reportedly devastating him.  By the time he was a teenager, Darin could play several instruments, including piano, drums, and guitar. He later added harmonica and xylophone.  Darin moved to the Bronx early in his life (with a rented summer home in Staten Island) and graduated from the prestigious Bronx High School of Science. In later years he attributed his arrogance to his experiences there, where he was surrounded by brighter students who teased him. He then enrolled at Hunter College and soon gravitated to the drama department. After only two semesters, he dropped out to pursue an acting career.
