‘Behaviour' was Pet Shop Boys' fourth studio album, recorded largely in Munich, Germany at producer Harold Faltermeyer's studio. The album was then completed at London's Sarm West Studios, and was released in October 1990 - hitting number two on the UK Album Chart and going on to earn platinum certification.

The LP is seen by some as one of Pet Shop Boys' most contemplative and moving records, and features the singles ‘So hard', ‘How can you expect to be taken seriously?' and their classic track ‘Being boring'. This ‘Catalogue' release of ‘Behaviour' features Further listening bonus tracks such as an extended mix of ‘Where the streets have no name (I can't take my eyes off you)' and an ambient mix of ‘Music for boys' - both of which are previously unreleased on CD.
