Johnny Burnette was born to Willie May and Dorsey Burnett Sr. in Memphis, Tennessee. (The "e" at the end of his name was added later.) Johnny grew up with his parents and Dorsey Jr. in a public housing project in the Lauderdale Courts area of Memphis, which from 1948 until 1954 was also the home of Gladys and Vernon Presley and their son, Elvis.

In 1952, the Burnette brothers and Burlison formed a group called the Rhythm Rangers. Johnny sang and played acoustic guitar, Dorsey played bass and Paul Burlison played lead guitar. For economic reasons, the three moved to New York in 1956 and managed to get an audition for Ted Mack's Original Amateur Hour. Winning the competition three times in a row gained them a place in the finals and a recording contract with Coral Records, and they renamed themselves the Rock and Roll Trio. They also gained a manager, the bandleader Henry Jerome, and a drummer, Tony Austin (a cousin of Carl Perkins).  Promotional appearances were arranged on Dick Clark's American Bandstand, Steve Allen's Tonight Show and Perry Como's Kraft Music Hall, together with a summer tour with Carl Perkins and Gene Vincent. On Sunday September 9, 1956, they appeared as finalists in the Original Amateur Hour at Madison Square Garden. Despite this activity, the three singles they released over this period failed to make the national charts.  In order to cover their living expenses, the Trio was forced to go on the road, for what seemed to be an endless stream of one-night stands. This exhausting regime led to squabbles, which were exacerbated in Dorsey's case by Jerome's use of the name Johnny Burnette and the Rock and Roll Trio on records and live dates. Things finally came to a head at a gig in Niagara Falls in autumn 1956, when, as a result of a fight, Dorsey quit the group a week before they were to appear in Alan Freed's film Rock, Rock, Rock.  Johnny Black, the brother of Elvis's bassist Bill Black, was rapidly recruited to fill Dorsey's place. Despite the film appearance and three more single releases and one LP release, the group failed to achieve any chart success. The Rock and Roll Trio disbanded in autumn 1957.Answer this question using a quote from the following article:
