-I am a rock
-You`ll never walk alone
I think that the song "You`ll never walk alone" and the poem "No Man is an Island" has the same meaning and message. This song and poem is about that everyone is together and that you will never be alone. It is always someone who will stand by your side even when there is thousands against you. The song "I am a rock" is more about being alone and that no one is there fore you. I think that the person in the song feels sand and that he thinks that no one is there fore him. But that he has to keep it inside him self.
