It was brought to my attention by a friend who attended the most recent Worldfest in Grass Valley that Bruce Hornsby is now employing a washboard player. A little Intertubular research proved that this is, indeed, the case.
Sonny Emory is the drummer for Bruce Hornsby and the Noisemakers, and he sometimes straps on a cajun-style rubboard and digs in. In the video up above, you can see him lay down a subtle, driving groove behind Hornsby singing a kind of back-porch-funk version of “Super Freak.”

Washboards are everywhere now.
