Someone else's story (chess in concert)

Long ago...
In someone else's lifetime
Someone with my name
Who looked a lot like me
Came to know
A man and made a promise
He only had to say
And that's where she would be.
Lately,
Although her feelings run just as deep,
The promise she made has grown impossible to keep
And yet I wish it wasn't so
Will he miss me if I go?

In a way
It's someone else's story
I don't see myself
As taking part at all
Yesterday
The girl that I was fond of
Finally could see
The writing on the wall
Sadly she realized she'd left him behind
And sadder than that she knew he wouldn't even mind
And though there's nothing left to say
Would he listen if I stay?

It's all very well to say 'You fool, it's now or never'
I could be choosing
No choices whatsoever

I could be
In someone else's story
Someone else's life
And he could be in mine
I don't see
A reason to be lonely
I should take my chances
Further down the line
And if that girl I knew should ask my advice...
Oh! I wouldn't hesitate
She needn't ask me twice
'Go now!'
I'd tell her that for free
The trouble is, the girl is me
The story is, the girl is me.
