Help this song has suddenly slipped my mind...?

It's called "Lady in Red".

Lady in Red - Chris DeBurgh

I've never seen you looking so lovely as you did tonight

I've never seen you shine so bright

I've never seen so many men ask you if you wanted to dance

They're looking for a little romance

Given half a chance

And I've never seen that dress you're wearing

Or that highlights in your hair

That catch your eyes

I have been blind

CHORUS:

The lady in red is dancing with me

Cheek to cheek

There's nobody here

It's just you and me

It's where I wanna be

But I hardly know this beauty by my side

I'll never forget the way you look tonight

I've never seen you looking so gorgeous as you did tonight

I've never seen you shine so bright you were amazing

I've never seen so many people want to be there by your side

And when you turned to me and smiled it took my breath away

And I have never had such a feeling such a feeling

Of complete and utter love, as I do tonight

CHORUS

I never will forget the way you look tonight

The lady in red

My lady in red

I love you...

Its called the Lady in Red.

sounds like Lady In Red to me

Here is a link to the lyrics

Hope that helps
