On 22nd August 1969, Led Zeppelin played Pirates' World, which suited their buccaneering spirit. Yo ho ho and a bottle of rum! When in Miami, the band stayed at the Doral hotel, which had a cocktail lounge nightclub in the basement. They got to hear Little Richard and his band in the club environment and boy were they good. It's Little Richard's songs that pioneered rock'n'roll. With Elvis singing them, this black music source just went under the radar during a racist period of time. That was taken from Jimmy Page's website.
