Behaviour, the Pet Shop Boys fifth LP was released 22 October 1990. It was recorded in Munich and co-produced by Harold Faltermeyer who they originally chose because they were interested in using old analog synthesisers. On two songs, “This must be the place I waited years to leave” and “My October symphony”, Johnny Marr plays guitar. Though at the time of the release they didn’t consider it to reflect a substantial shift in mood, later they conceded it had been. “It was more reflective and more musical-sounding, and also it probably didn’t have irritatingly crass ideas in it, like our songs often do”.
