I really enjoyed these videos and Bruce seems in great form, however, I think he is being far too modest with regard to his chord skills, whether he knows what they are called or not!! I watched a few YouTube clips including one I found of them playing Chelsea Boot back in the late '60s, and you can clearly see Bruce barreing the odd chord. And then, what about those tracks which feature semi-tone key-changes - there must have been a few Bbs and Ebs there, not to mention those tracks with diminished and augmented chords. He is definitely the Guv'nor when it comes to rhythm and chord progressions although I agreed he is not into the jazzy type of work.
