The way that Karen sings "long ago, and so very far away" pierces my soul, somehow, transcending time and sending me back to the long carpet, record burbling on the stereo. Maybe it's the first song I could grasp as "song." But it's also that the voice, the voice is supernatural, it is the aural explication of yearning. It expresses and explains longing at all the same time.
Those three words immediately push out tears from I-don't-know-where.
I should add that this is what I assume to be one of the rare times Karen is seen playing drums, which was something she loved to do.
