Wow, I’m not sure how I screwed up on the origin of the song… I guess that’s what happens when a guy has a couple too many beers before posting… A friend stopped by yesterday, and he asked me what I thought of a Hughes & Kettner amp I picked up a little while back that he hadn’t seen before, so I picked up a guitar and played that one for him… He went, “Ah, the old Zep tune that Sonny Boy Williamson wrote”, and I guess it got stuck in my head for a while… But it was still a bit embarrassing to get the facts wrong on a song that I have always loved, and I actually have a copy of the song from when Willie Dixon put it out in 63 that also has Matt “Guitar” Murphy on guitar… So I should have known better, but lesson learned though, post sober… 
So anyways, afterwards the thought occurred to me there wasn’t a OPB for that one, so I thought I would put the idea out there… Thanks for giving it a look Phil_Flood,
