'It's A Sin' was the first single released from 'Actually', before the full album release. A highly dramatic production, it is a track that has come to be easily recognizable as Pet Shop Boys, as much as 'West End Girls'. It was originally conceived and written in 1982. Remixes were done by Ian Levine and Phil Harding. The b-side was 'You Know Where You Went Wrong'. "It's A Sin" marks the start of Pet Shop Boys' Imperial phase.
