A Lover Is Blue lyrics

Yesterday we were gay,
I was high on a rainbow, but now there's no rainbow,
You've gone, and so a lover is blue.
Life was sweet, so complete,
Now I've suddenly waken to find I'm forsaken,
Alone, and so a lover is blue.
Do you still remember our love affair,
Does it matter to you,
But I'll have to go through our door to care.
Here and there everywhere,
Every scene just reminds me
Of something that binds me
To you, and so a lover is blue.
