完整歌词节选：

```

I will lay down next to you

Stay in bed all afternoon

We were the birds of a feather

We were always together

And I never will forget

All the little things you said

In that beautiful summer

Used to call me your lovebird

But the time went on

The wind has blown

And I have grown

And I started a feeling

That my wings have been broken

And I can't believe

That I would ever want to be set free

But I just can't stay

So your lovebird's flying away

Your love is flying away

'Cause my heart's been stuck in a cage

Got to sing my song

So pretty

Dum dum diddy

And I miss you

```
