There were moments of gold
And there were flashes of light
There were things I'd never do again
But then they'd always seemed right
There were nights of endless pleasure
It was more than any laws allow
If I kiss you like this
And if you whisper like that
It was lost long ago, but it's all coming back to me
If you want me like this
And if you need me like that
It was dead long ago, but it's all coming back to me
It's so hard to resist, and it's all coming back to me
I can barely recall, but it's all coming back to me now
