I found a great performance clip from the old Night Music show that was hosted by David Sanborn on youtube with Hiram Bullock on rhythm guitar:
"There is no royal road to this heavy surf-fishing. With all the appliances for comfort experience can suggest, there is a certain amount of hard work to be done and exposure to be bourne as a part of the price of success." From "Striped Bass," Scribner's Magazine, 1881.
