"ABC" is a 1970 number-one hit song by The Jackson 5. "ABC" was written with the same design as "I Want You Back", and was first heard on American Bandstand in February 1970. "ABC" knocked The Beatles song "Let It Be" out of the number one spot on the Billboard Hot 100 in 1970. "ABC" was also number one on the soul singles chart for four weeks.
"ABC" was the first single from the second Jackson 5 album, ABC. It is considered one of the Jackson 5's signature songs.
The song is used on British commercials for Nestle's Aero, and was memorably featured in the 2006 film Clerks II. It is part of the soundtrack for the Disney Channel Original Series Lizzie McGuire, and is also on the teaser for the film Daddy Day Care. In 2009, the song was parodied by The Fringemunks to recap Fringe episode 1.14, "Ability."
