Words and Music by Branislau Kaper and Helen Deutsch  A song of love is a sad song, Hi-Lili, Hi-Lili, Hi-Lo  A song of love is a song of woe  Don't ask me how I know  A song of love is a sad song  For I have loved and it's so  I sit at the window and watch the rain, Hi-Lili, Hi-Lili, Hi-Lo  Tomorrow I'll probably love again, Hi-Lili, Hi-Lili, Hi-Lo.    A song of love is a sad song, Hi-Lili, Hi-Lili, Hi-Lo  A song of love is a song of woe  Don't ask me how I know  A song of love is a sad song  For I have loved and it's so  I sit at the window and watch the rain, Hi-Lili, Hi-Lili, Hi-Lo  Tomorrow I'll probably love again, Hi-Lili----Hi-Lili----Hi-Lo.
