Yes, yes, we know the Pet Shop Boys have been a bit crap for a while now. But when they were good, they were really bloody good. Their fourth LP Behaviour, first released in 1990, is the one that would probably win if you took a straw-poll among hardcore PSB fans as to which was the duo’s best full-length. It’s a gorgeous, wistful sigh of a record. Any album that starts with ‘Being Boring’ is going to be up to something, right?
