Sometimes the world
tries to knock it out of you
But I believe in music
the way that some people
believe in fairy tales.
I like to imagine that what I hear
came from my mother and father.
Maybe the notes I hear...
are the same ones
they heard the night they met.
Maybe that's how they found each other.
Maybe that's how they'll find me.
I believe that,
once upon a time long ago
they heard the music and followed it.
