In A Radio Song Lyrics

Cover art for In A Radio Song lyrics by Okkervil River

What is the sound that sometimes pops up between verses? Sounds like something steam powered... I take the bus a lot, and associate the sound to the giant-ass windshield wipers that use air pressure to work. I dunno, I really like that sound, but the bus windshield wipers are actually really fucking annoying. Strange.

Come to think of it, it sounds more like this bicycle pump I used to have that was used by stepping on it. The squeaking of it as you pressed down and released, and the release of the air as you stepped off.
