There are several corridos about Jaramillo that can be found with google. Enter
"Ruben Jaramillo" corrido

I won't post, because I don't have translations. They seem to be of two types; early ones about events from 1915-1940, and late ones encompassing his death.

There are a number of volumes of corridos, covering many hundreds, revolutionary and otherwise, published in Mexico. They are almost impossible to find because editions were very small. Contents of some of then may be found through google.
