I couldn't find the lyrics for this song anywhere on the Internet. I ended up typing them up and am saving them here for future reference.

Thousands of Miles
from "Lost in the Stars"

Words by Maxwell Anderson
Music by Kurt Weill

How many miles to the heart of a child?
Thousands of mile, thousands of miles.
When he lay on your breast, he looked up and smiled
across tens of thousands, thousands of miles.

Each lives alone in a world of dark,
Crossing the skies in a lonely arc,
Save when love leaps out like a leaping spark
over thousands, thousands of miles.

Not miles, or walls, or length of days,
Nor the cold doubt of midnight can hold us apart.
For swifter than wings of the morning,
The pathways of the heart.

How many miles to the heart of a son?
Thousands of miles, thousands of miles.
Farther off than the rails or the roadways run
across tens of thousands, thousands of miles.

The lines on the map stretch far and thin,
To the streets and days that close him in,
But then as of old he turns ‘round to grin
over thousands, thousands of miles

Not miles or walls or length of days,
Nor the cold doubt of midnight can hold us apart.
For swifter than wings of the morning.
The pathways of the heart
Over tens of thousands of miles.
