The Sisters of Mercy were a popular English goth band who did very well in the UK between 1984 and 1993. In 1985, tensions in the band led to their split, with bass player Craig Adams and guitarist Wayne Hussey
leaving to form The Mission. The Sisters Of Mercy leader Andrew Eldritch re-formed the band in 1987, without Adams and Hussey. This song takes a stab at the departed pair, with lines like "Sing this corrosion to me" and "Selling the don't belong," indicating that Eldritch considered The Mission's sound to be a copy - or corrosive version - of The Sisters Of Mercy.
The Mission went on to have a successful chart career in the UK, with hit singles like "Wasteland," "Tower of Strength
" and "Butterfly On A Wheel."
