I know you.
I've seen you in a dream ,
an old familiar scene, from somewhere...

You know me.
There's glowing in your eyes,
a glow I recognize, from somewhere...

Those voices, 
singing out,
"La, la, la, la, la..."

LILY & JAMES: 

La, la, la, la, la...

HARRY, LILY & JAMES:

La, la, la, la, la... la.

SIRIUS:

I see them.
They were people that I loved,
you were barely old enough
to be there.

But I know you.
You have your mothers eyes,
beneath your dad's untidy dark hair.

Those voices,
ringing out,
"La, la, la, la, la..."

LILY & JAMES: 

La, la, la, la, la...

SIRIUS, LILY & JAMES:

La, la, la, la, la... 

SIRIUS:

I would never do
anything that could hurt you!
They were both my family!

You're all that's left of what I knew,
you must know somewhere that it's [bad word] 
Do you understand me?

HARRY:

[spoken] "Yeah, I do."

HARRY & SIRIUS:

those voies
reaching out,
"La, la, la, la, la..."

LILY & JAMES: 

La, la, la, la, la...

HARRY & SIRIUS, LILY & JAMES:

La, la, la, la, la... La.
