Colin Hay：Meaning of Who Can It Be Now? Songmeaning

The song "Who Can It Be Now?" by Colin Hay tells the story of a person who is trying to be left alone but keeps getting bothered by someone knocking at their door. The person is tired and not feeling well, and just wants to be left alone to rest. They are afraid that if the person outside hears them, they will continue to knock and they'll be trapped. The person singing has done nothing wrong and wants to be left in peace. They start to question whether the person outside is there to take them away. The song suggests that the person outside may just be a figment of the singer's imagination, and that the fear is all in their head. The song is relatable because many people can identify with the desire for solitude and the fear of being bothered or intruded upon.
