Ashlee Simpson appeared as a musical guest on Episode 568 of Saturday Night Live (October 23–24, 2004), and, as is customary for the show's format, she was scheduled to perform two songs. Her first song, "Pieces of Me," was performed without problems. However, when Ashlee Simpson began her second song, "Autobiography," the vocals for the song "Pieces of Me" were heard again—before she had even raised the microphone to her mouth. Ashlee Simpson began to do an impromptu jig when she realized the embarrassing error, but then left the stage. During the closing of the show Ashlee Simpson appeared with the guest host Jude Law and said, "I'm so sorry. My band started playing the wrong song, and I didn't know what to do, so I thought I'd do a hoedown."
