The paper presents certain contemporary observations by Paul McCartney on his own song lyrics written during his creative periods with The Beatles, Wings, as a solo artist, and in collaboration with other artists. The article traces the relations between specificity and openness of the interpretation, as well as the deliberate and spontaneously originated polysemy. Paul McCartney's auto-reflexivity is examined not only as a form of autobiographicality, which it inevitably is, but also as a manifestation of various aspects of literariness.
