"Back in the U.S.A." is a song by Chuck Berry, which was first issued in 1959 as a single a-side and on Berry's 1962 album More Chuck Berry, (both Chess Records). The song's lyrics were supposedly written based upon Berry returning to the USA following a trip to Australia and witnessing the living standards of Australian Aborigines.
The song has been recorded by many artists. MC5 covered the song in 1970 on their second album, also titled Back in the USA. In 1972, a live version of the song appeared on the album Roadwork by Edgar Winter's White Trash. The song was covered by Jonathan Richman and the Modern Lovers in 1976 on their self-titled second album. The song received its biggest commercial success when Linda Ronstadt included it in her 1978 double platinum album Living in the USA. The single got as high as #11 in Cash Box and reached #16 on the Billboard Hot 100 chart. (It was Top Five in the Detroit market place.) Ronstadt performed the song with Berry and Keith Richards in the feature film, Hail! Hail! Rock 'n' Roll. Gene Summers included "Back In The USA" on his 1983 album 'Live' In Scandinavia, and he has also used the song as his opening number on numerous occasions. 
"Back in the USA" was famously parodied by The Beatles with their song "Back in the U.S.S.R." from their self-titled 1968 album The Beatles (aka the White Album).
Chris Robinson and Rich Robinson of The Black Crowes performed this song during Berry's induction into the Kennedy Center Honors in 2000.
In Kidsongs "Sing Out, America!", the song title is called "Living in the USA" instead of "Back in the USA".
