SMILE （by Bharlie Chaplin） Smile tho' your heart is aching smile even tho' it's breaking when there are clauds in the sky you'll get by if you smile through your fear and sorrow smile and maybe tomorrow you'll see the sun come shining thru for you. Light up your face with gladness hide ev'ry trace of sadness altho' a tear maybe ever so near that's the time you must keep on trying smile what's the use of crying you'll find that life is stillworth while if you'll just smile.
