Answer 1

To many people in the music and entertainment industry, Elvis Presley is often noted as the King of Rock n Roll and references in print usually are referring to him when that "title" is used.

Other fans have their own opinions about their pick as the Rock and Roll "King".

Better known perhaps as the Father of Rock n Roll or Originator of Rock n Roll is Bill Haley of Bill Haley and his Comets. Bill Haley started Rock and Roll in 1953 when Elvis Presley was still in the 11th grade. Some people refer to him as the Real King of Rock and Roll.
