Richard's producer, Bumps Blackwell, had him record the vocal exceptionally fast in an effort to thwart Pat Boone. Boone's version of "Tutti Frutti
" sold better than Little Richard's, so Blackwell tried to make it very difficult for Boone to copy. He had Richard work on the line "duck back down the alley" over and over until he could sing it very fast. He figured Boone could never match Richard's vocal dexterity.
Despite the efforts of Blackwell, Boone covered the song in 1956. His version was very clean and sterile, making it acceptable to white audiences who couldn't handle Little Richard. Unlike his cover of "Tutti Frutti," however, his version was not a bigger hit than the original - it hit #8 in the US.
Richard's delivery did help get his song past some censors, however. A standards and practices guy at NBC once said, "How can I reject it when I can't even understand it?"
