Yeah. It's important that you say that, because a lot of people give . . . they credit people like Coleman Hawkins with starting that on the saxophone, that stuff, and I thought that that had started earlier. Let me ask you this: you think, then, that it was very important, those years that Louis Armstrong spent on the Capitol with Fate Marable's  band, because you hear in the middle and late '20s, when he started making his own Hot Five and Hot Seven recordings, him using quite a lot of, running a lot of chords, and playing augmented and diminished chords, and all those things, when not a whole lot of other people were doing that.
