"Perfect Strangers" is a song by the British hard rock band Deep Purple. It is the title track of their 1984 comeback album Perfect Strangers. This song is about reincarnation. It's a conversation between oneself from their past life and their present self. The song tells about memories this person has from their past life, but they (past and present self) "must remain perfect strangers" to each other. It is one of the few Deep Purple songs not to feature a guitar solo. Nevertheless, band guitarist Ritchie Blackmore has called it his favorite Deep Purple song.
