DAY 43: HAVE A GUESS. . . .

On every tree there sits a bird

Singing 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
Hi-lili, hi-lili, hi-lo
Tomorrow I'll probably love again

 Hi-lili, hi-lili, hi-lo

I wonder how many will remember who sang this song, and the name of the movie?
