"Monkey and the Engineer" is a Jesse "Lone Cat" Davis song. He was a one-man band in San Francisco and all the Bay area musicians loved him. Based on your profile pic and your location, you're probably familiar.
I love train songs. I do a lot of them. Probably half of my song list is songs either about trains or referring to trains in some way.
I don't do Terrapin, though.
