When performed live, the song would usually go for 8 minutes in length. A very well known depiction of this peformace was during the Mirage tour in 1982. The song was referred to as the "speaking in tongues" performance in which Stevie Nicks delivers the song's coda in such an intense, gravelly manner that her words become incomprehendable. The video was regarded as one of Nicks' finest live performances by her fanbase.
Fleetwood Mac played this song since 1982 on April 4, 2013 at their concert in Columbus, Ohio.
