Yes, he seemed both a bit smarter and more musically proficient than you would guess from his public persona.
Still just as roasted as you would expect though :)
The part that impressed me was when he started jamming that piano boogie woogie that Ian Stuart taught him. I’m a piano player, and boogie woogie is not beginner level stuff, but Keef played it off like it was just some little thing he picked up casually. That tells me he’s just a natural musician and could probably learn any instrument he wanted if he just bothered to spend a little time on it.
Piano palying shocked me...His voice may not have been bad 30 years ago!
