Doin’ what they do, shepherding her through
Space will slow her stride, time will turn her tide
It’s far too much to take, but my girl don’t know when to break
So she’ll make she’ll make a way; she’s a good old girl, she’ll fly true

“Good Old Girl,” by Marian Call

Gotta love a song about spaceships.  I think this was specifically inspired by Firefly, but it’s pretty general in a way I really like.
