Granddaddy always said

When he was seventeen he met the girl

The one in all his dreams

And man that was it

He never once looked back

He found something

He just knew was gonna last

And if you ask him 'bout that day

He'll just tap his chest and say.

[Chorus]

That's how you know

When it grabs a hold of you and won't let go

When you feel like she's always been in your soul

And as time goes by she's still surprisin' you

That's how you know it's true

When a new love feels old

And an old love feels new.

He said I walked up to her door

And I was shakin' like a leaf there on her porch

'til she flashed that smile at me

And son she took my breath away

And she still does to this day.

[Chorus]

That's how you know

When it grabs a hold of you and won't let go

When you feel like she's always been in your soul

And as time goes by she's still surprisin' you

That's how you know it's true

When a new love feels old

And an old love feels new.

And now I finally see

Just what he means

'cause that's how I feel now that you're with me

That's how I know

'cause you grabbed a hold of me and won't let go

And it feels like you've always been in my soul.

[Chorus]

That's how you know

When it grabs a hold of you and won't let go

When you feel like she's always been in your soul

And as time goes by she's still surprisin' you

That's how you know it's true

When a new love feels old

And an old love feels new.
