"Carefree" is a football chant, sung by followers of the Chelsea football club, mainly at away games, and meant to demonstrate indifference and possibly belligerence when in an alien, hostile environment. The original tune is "Lord of the Dance".
Lyrics
The chant was first sung on a trip of fans to an away game in Sweden, ca. 1982. The lyrics were probably put together by a terrace regular named Mick Greenaway.
Carefree, wherever we may beWe are the famous CFCAnd we don't careWhoever you may be'Cause we are the famous CFCUsually, the chant is sung with bawdier lyrics.
