“You're bound to get idears if you go thinkin' about stuff”

The Grapes of Wrath is a book I've been inspired to put on my shortlist since I realised that I had a few songs in my record collection which were inspired by the book and the John Ford film adaptation.

Having looked the book up, it seems it would be a timely read at the moment too....

"No, you’re wrong there—quite wrong there. The bank is something else than men. It happens that every man in a bank hates what the bank does, and yet the bank does it. The bank is something more than men, I tell you. It’s the monster. Men made it, but they can’t control it.”

Are there many other books that have inspired lots of songs down through the decades like this?
