nothing but a face in the crowd

I'm reading Nicholas Sparks' "The lucky one" at the moment. It's about a guy who has only got a photo of the girl he now intends to search out. Somewhere I came across the line "nothing but a face in the crowd" that somehow stroke the romantic chord in me. The title I came up with goes "I've waited for you to happen" (I jumped out of the bed to put the chorus down instantly so as not to forget it):

my life dragged on
only my dreams seemed real
nothing to look forward to
I was just spinning wheels

then I saw you -
a gorgeous face in the crowd
should have stopped you there and then
I should have called out loud

'cos
all my life
yeah, all my life
I've waited for you to happen

(I) spent days and months
trying to search you out
striding up and down the very path
that you'd first come about

'cos
all my life
yeah, all my life
I've waited for you to happen

I was short of giving up
when in the most unlikely place,
on my day-to-day commuter bus,
I'd spot your pretty face
I grabbed your arm urging you
to sit down by my side
I didn't want to upset you
yet I'd to put things right

'cos
all my life
yeah, all my life
I've waited for you to happen

all my life
yeah, all my life
I've waited for you to happen
