作词 : Arnold, Martin, Morrow You know I can't smile without you I can't smile without you I can't laugh and I can't sing I'm finding it hard to do anything You see I feel sad when you're sad I feel glad when you're glad If you only knew what I'm going through I just can't smile without you You came along just like a song And brightened my day Who would believe that you're part of a dream Now it all seems light years away You know I can't smile without you I can't smile without you I can't laugh and I can't sing I'm finding it hard to do anything You see I feel sad when you're sad I feel glad when you're glad If you only knew what I'm going through I just can't smile Some people say happiness takes So very long to find But I'm finding it hard Leaving your love behind me, so you see I can't smile without you I can't smile without you I can't laugh and I can't sing I'm finding it hard to do anything You see I feel glad when you're glad I feel sad when you're sad If you only knew what I'm going through I just can't smile without you
