I found this video http://www.youtube.com/watch?v=IPW9siuSfoU of Sammy's Bar on You Tube

From "Flipping the Whale" (2000), written and directed by Sean Guinan, produced by Joshua Eckhardt and Sean Guinan. With Eddie Shin, Amy Bakos and Sean Guinan. The song was written by Cyril Tawney and recorded by the Golden Ring, a short-lived Chicago folk group from the early 70s.

Does anybody know anything about them?
