The video was directed by Eric Watson. The b-side was the Pet Shop Boys' tidied-up demo version of "Losing My Mind", which they produced for Liza Minnelli in 1989 for her album "Results". The single mix was more electronic than the version on the album, and there was an extended mix of "Jealousy" which featured Neil Tennant reading excerpts of Shakespeare's Othello, which is a play about jealousy. There was also a Disco Mix of "Losing My Mind". On the limited edition CD, an edit of the Extended Mix of "This Must Be the Place I Waited Years to Leave" (which was originally available with the Japanese version of "Behaviour") was included along with David Morales' Red Zone mix of "So Hard". "Jealousy" was later covered by Dubstar. It is known to be one of Robbie Williams' favourite Pet Shop Boys songs, and he sang it with the duo for their 2006 Radio 2 concert, which was later released on the 2006 Pet Shop Boys' live album "Concrete".
