Here's an mp3 (2:34, 3.0 MB, 160 kbps) which was digitally ripped from the DVD. Enjoy.
Doolittle: Let's have some music in here, Boiler.
Boiler: Sure thing!
Benson, Arizona, the warm wind through your hair
My body flies the galaxies, my heart longs to be there
Benson, Arizona, the same stars in the sky
But they seemed so much kinder when we watched them, you and I
Now the years pull us apart
I'm young and now you're old
But you're still in my heart
And the memory won't grow cold
I dream of times and spaces
I left far behind
Where we spent our last few days
Benson's on my mind
