I don't why. but when I played this, I choked up and almost burst into tears. Later I played it for for Mrs.Fusion, and it happened again. Some kind of past life connection? I have no memory associated with it.

Lyrics from the Wikipedia page; these are similar to what they sing:

~~~~~~~~~~~~~~~~~~
Oh Shenandoah,

I long to see you,
Away, you rolling river.
Oh Shenandoah,
I long to see you,
Way, we're bound away
Across the wide Missouri.

Oh Shenandoah,
I love your daughter,
Away, you rolling river.
For her I'd cross
Your roaming waters,
Way, we're bound away
Across the wide Missouri.

'Tis seven years
since last I've seen you,
Away, you rolling river.
'Tis seven years
since last I've seen you,
Way, we're bound away
Across the wide Missouri.

Oh Shenandoah,
I long to hear you,
And hear your rolling river.
Oh Shenandoah,
I long to hear you,
Way, we're bound away
Across the wide Missouri.

Oh Shenandoah,
I long to hear you,
Far away, you rolling river.
Oh Shenandoah,
Just to be near you,
Far away, far away.
Across the wide Missouri.
