(Jagger/Richards). Why does the sky turn grey ev'ry night. Sun rise again in time. Why do you think of the first girl you had. Some things just stick in your mind. Why does the rain fall down on the earth. Why do the clouds keep cryin'. Why do you sleep curled up like a child. Some things just stick in your mind. Why when the children grow up and leave. Still remember their nursery rhymes. Why must there be so much hate in their lives. Some things just stick in their minds.
