Actually, Redd, that vid is mislabeled. it's not Miles at all, but Chet Baker.
I knew it wasn't Miles after about 10 seconds--just not his sound. Beautiful, but not Miles. An actually, I'm sort of relieved. The idea of Miles doing "Smoke" sort of had me prepared for something rather different, especially considering the photo at the beginning of that vid is from Miles' later career, when he was in his h.e.r.o.i.n junkie, "I Hate Whitey" phase, and was playing really weird, angry stuff...
Not your fault, and not trying to be obnoxious--it could happen to anyone. That's the problem with YouTube--a lot of people post stuff and they mislabel it because they have no idea what it really is...
