"Rockin' Pneumonia and the Boogie Woogie Flu" is a song written and originally recorded in 1957 by Huey 'Piano' Smith, who scored a minor Billboard hit with it, peaking at No.

[1] The title is a reference to "walking" pneumonia and the Asian flu, which hit the United States in 1957–58.

The lyrics recount the predicament of the singer who would like to approach a woman he sees in a club (or "joint"), but is unsuccessful due to his musical ailments.

1972 saw the song become an international hit single for Johnny Rivers, featuring Larry Knechtel on piano as well as other Los Angeles session musicians from the Wrecking Crew.

His final gold record would be with the 1977 hit, "Swayin' to the Music (Slow Dancing)."
