The album was originally released on
EMI's
Harvest Records label (SHVL820) in 1980 (also
Harvest ST6474 (CAN) and
Electrola 1C06407259 (FRG)). In 1998 the album was reissued on Harper's
Science Friction label (HUCD031). Whilst duets are not commonplace on
Roy Harper albums,
Kate Bush accompanies Harper on the song "You". The song "Short and Sweet" features
David Gilmour on guitar and is also found on Gilmour's first solo album,
David Gilmour, released two years earlier. Harper also sang the song as a guest at one of Gilmour's 1984 concerts in London. Originally, the songs "I'm in Love with You", "Ten Years Ago" and "The Flycatcher", were to be released on the proposed earlier (1978–79) Harper album,
Commercial Breaks. However, a dispute between Harper and
EMI meant
Commercial Breaks was not released until 1994. These three songs were re-recorded for
The Unknown Soldier, and vary slightly from their original demo composition. ==Track listing==
