On every tree there sits a bird Singin' a song of love On every tree there sits a bird And every one I ever heard Could break my heart without a word Singing a song of love 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 (Oo oo oo oo oo oo oo oo) Hi-lili, hi-lili, hi-lo (Oo oo oo oo oo oo oo oo oo) Tomorrow I'll probably love again (Lili lili lili loo) Hi-lili, hi-lili, hi-lo (Oo oo) Tomorrow I'll probably love again (Lili lili lili loo) Hi-lili, hi-lili, hi-lo (Oo oo oo oo)
