Before Bo Diddley created a signature sound of his own, the first-gen rocker soaked up the same country, R&B, and New Orleans influences as a lot of his peers. You can hear it in his jumping update of country classic "Sixteen Tons" just as strongly as you can in his Duane-Eddy-goes-to-Mardi-Gras takeover of the New Orleans standard "When the Saints Go Marching In," all of it somehow sounding like nothing but Bo Diddley music from start to finish.
