In September 1957 Arkansas Democratic Governor Orval E. Faubus became the national symbol of racial segregation when he used Arkansas National Guardsmen to block the enrollment of nine black students who had been ordered by a federal judge to desegregate Little Rock's Central High School. His action created a national crisis with President Dwight D. Eisenhower finally ordering federal troops to Little Rock to ensure the judge's order was obeyed, to protect the black students, and maintain order for the remainder of the school year.
In both 1959 and 1960, many staff members at the Cleveland "r&b" radio station where I worked went to Mississippi to help register voters. I was in the group in 1960 that went to Newton, MS, near Meridian, where there had been violence and protests going back several years.
The reason why Elvis' first appearance on Ed Sullivan's show was "waist up" only had to do with the protests that his movements were lewd and the music was inspired by the devil.
