You are

This broken wheel is coming undone And the roads exploding But you're keeping me strong Rolling along with you,... Love is a tower And you're the key Leading me higher When you let me in Keeping us close,... so close On down the line Sometimes I burn like a dot on the sun With no one knowing But you're keeping me strong Rolling along with you You are a tower of Strength to me The darkening hour Sees light again Ooh wah, ooh wah, you are... Love is a tower Of strength to me I am the shoreline But you're the sea You are.
