Former postal worker Godfrey made his living performing in small bars and coffee houses in and around Boston, Massachusetts for more than a decade until the MYSTIC RIVER star "discovered" him in Memphis, Tennessee two years ago.
Since then, Godfrey has hung out with Penn on the sets of four movies, filmed a cameo in the actor's upcoming film The Assassination of Richard Nixon and performed with his band at the wrap party for 21 GRAMS.
Godfrey, 48, says, "I'm the son of a fireman from a poor neighbourhood called Whiskey Point. And I believe Sean really relates with blue-collar, working class people who drag their a** out of bed every day and go to work in real-life America. That's what my songs are all about."
