Enola Gay is identical to the versions on the 7" release and also on the Organisation album.

The sleeve designs for the 7" and 12" differ only from slight changes in the tone of the background and the wording being picked out in white on the 12".

The Enola Gay was the name of the B-29 bomber that dropped the first atomic bomb on the Japanese city of Hiroshima in August 1945. The pilot of the plane, Paul Tibbetts, had named the plane after his mother.
