Lyrics:

It's someone else,
I've known it all the time
Known that you're not mine,
And will never be
It's Someone Else,
I saw you out last night
Holding him so tight,
And it's Someone Else.

No I really can't hate him,
For what's happening to me
Will happen to him -
That's a certainty.

And he'll learn
There's always someone else
Like I learned myself,
Always Someone Else
Always Someone Else
