Spratleys Japs were an English psychedelic rock band formed by Cardiacs leader Tim Smith and Joanne Spratley. The band were known to have been inspired by the sound of a malfunctioning Mellotron loaned to Tim Smith by Planet Mellotron coordinator Andy Thompson. The Mellotron is used extensively on the Spratleys Japs recordings. (It has since been repaired). The band released one album - 1998's Pony - and one single - 1999's "Hazel". Both of these were released on Smith's own All My Eye And Betty Martin Music label. There have been no further releases since then.
