The version of Hiroshima Mon Amour exclusive to this 4-track cassette single and the associated 3-track 7-inch single (released a week earlier on Monday, 2 March 1981) is an alternate mix of the Ha! Ha! Ha! album version (as confirmed via personal correspondence with producer Steve Lillywhite). This "alternate mix" is currently only available on these two formats and has not been released on any other formats (e.g. compact disc or digital). Only the original ROckwrok B-side single version of the track has been made available on subsequent compact disc and digital format releases.
The release date for the compact disc of this album is Monday, 5 July 1986.
Despite the article within Record Mirror advising of a release date of Monday, 30 June 1986, according to the Music Week, 28 June 1986 (Page 31, "NEW ALBUMS") listing, only the cassette format was released on that date. Music Week has a separate listing for Monday, 7 July 1986 for the compact disc.
