GC Executive Committee theme song?

I've been working on the Railroad,
   All the live-long day.
I've been working on the Railroad,
   Just to pass the time away.

Can't you hear our PREXAD blowing,
   Policy here is born.
Can't you hear our Chairman shouting,
  GC blow your horn!

(Refrain)

GC won't you blow?
   . . .
