The song is taken from their forthcoming 40th anniversary career-spanning boxset and comprehensive singles collection 'Souvenir', which came out on October 4th via White Noise Records. Pre-order it here.
The band's words: "Liberator was a song that Andy had been trying to write for several years from the late 1980s to the mid 90s. Indeed it was intended as the title track to the 1993 album of the same name but never made it onto the album. The title inspiration comes from Andy's love of WWII aeroplanes. There were several demo versions recorded - the one released today is the nearest the song got to the intended sound.".
