Lyrics:

On every tree there sits a bird
Singing a song of love
On every tree there sits a bird
And every bird I've 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

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
