The song is reported to be the first CD single ever released.
It was re-released in 2007 as a special edition to commemorate the 25th anniversary of the Falklands War conflict and raise funds for veterans of it with post-traumatic stress disorder.
There are two studio recorded versions of this song: the album version which is 6:55 minutes, and the shorter version which is 6:05 minutes and features slightly different (and shorter) solos at the beginning and end of the song.
The version featured on the live album On the Night contains an extra pedal steel guitar solo and is 8:55.
It was released in the United Kingdom in 1985.
