Send In the Clowns

I've been given an interesting task (sort of): list my 15 favorite showtunes and explain why I like them.  The list was easy enough, but I didn't have a good version of "Send In the Clowns" from A Little Night Music.  After some searching (read: about and hour and a half), I wasn't able to find a good version on iTunes, either.  Which led me to the question: Why is that one of my favorite songs? In what setting had I heard it where it touched me so?

It was a performance.  A performance that I remember only half-listening to.  It was a showcase, I believe at high school festival.  They wheeled a couch and something else onto the stage.  There were 2 characters, male and female.  There was a fight.  He left.  Then she sang.  She wore red.  I have no idea who she was, what school they represented, or even if it was actually the scene from A Little Night Music.  I just remember that I fell in love.  I wish I could find a version like that.
