1955 – Little Richard enters a New Orleans studio to begin two days of recording. The sessions don’t start well, but they end fantastically. During a break, he and his producer Bumps Blackwell go to the Dew Drop Inn for lunch. Richard starts wildly playing the piano in the bar, singing a loud and lewd version of “Tutti Frutti.” With only fifteen minutes left in the session, Richard records this version of the song with the phrase, “a-wop-bop-a-loo-bop-a-lop-bam-boom.”
