One of the saddest songs I have heard is "The Leaves They Mustn't Fall."I do not recall who sang it nor do I recall most of the lyrics.Some of the lyrics following that line are
                  Oh no, they mustn't fall.
                  Please tie them on so they will stay.
                  I've lost my mom and dad,.now my sister's all I have.
                  Don't let the falling leaves take her away.
