"Lookin' Out My Back Door" was a direct tribute to the Bakersfield Sound, a form of music that influenced Fogerty and the CCR sound. Buck Owens, one of the architects of the Bakersfield Sound, is even mentioned in the song's lyrics.
The song's lyrics, filled with colorful, dream-like imagery, led some to believe that the song was about drugs. According to the drug theory, the "flying spoon" in the song was a reference to a cocaine or heroin spoon, and the crazy animal images were an acid trip. Fogerty, however, has stated in interviews that the song was actually written for his then three-year-old son, Josh. Fogerty has also said that the reference to a parade passing by was inspired by the Dr. Seuss book And to Think That I Saw It on Mulberry Street.
