The white disc jockey Alan Freed stated he had used the term, which originally meant having a secret lover on the side in black slang, in a musical context for the first time in 1951 in Cleveland, Ohio. As hard as it is to verify this claim, it is a fact that the term and style rock & roll from 1954 onwards beacme very popular over the New Yorker stations WINS and WABC. The line "Rock, rock, rock everybody, roll, roll, roll everybody" from Bill Haleys song "Rock A Beatin' Boogie", that Freed used as his signature tune for his shows, was obeyed by the youth of the whole country. The fusion of white Hillbilly and black Blues musik resulted in the biggest musical revolution of the 20th century.
