From the Wikipedia article for the Little Richard song "Long Tall Sally".
"Tutti Frutti" had been a big hit for Little Richard and Specialty in early 1956, reaching No. 2 in the R&B charts. Pat Boone's cover version of the song reached No. 12 in the pop charts. Although this meant an unexpected cash income for the Specialty publishing firm, A&R man and producer "Bumps" Blackwell and a proud Richard decided to write a song that was so up-tempo and the lyrics so fast that Boone would not be able to handle it (Boone eventually did record his own version, getting it to No. 8).
