I saw them last night on the Tonight Show. Southern rock band, sound kind of like George Thorogood & the Destroyers, and even had a name in the similar style (i.e. the name of the band was like "So and so (guys name) and the something-somethings (the rest of the band)". The song they played was called "Four Letter Word" or something like that. I think the guys last name was Nelson. I hope that's enough to go on..
