Well, Louis Armstrong ... only God can answer that question. I found out a lot of things about him but I met him accidentally, and he was very nice to me and his wife, and he helped me a lot and for what reason? All I did here I did because years ago he was not too friendly, I mean the musicians from New Orleans were not too friendly with him.  Because they were jealous because he was one man that came and outplayed everybody who had a horn. And they were jealous of that, of the way he played, and what his conception of jazz was. They never heard anything like it in their life. And a lot of them didn't like it because he received so much attention. And there was nobody in the world that could play like him, nobody had the knowledge of not only jazz, but everything else in music, than Louis Armstrong. He had a, I found out that in New Orleans, I met an old fellow down there, and there's not too many old people that knew him. I found an old fellow down there sitting down eating some corn flakes or potato chips on the sidewalk, and he looked up and he says, I had my horn and he says "you a musician? " I say "yeah. " He says "what do you play? " I tell him "I play cornet, I play trumpet. " He says "you    know Louis Armstrong? " I say "yeah, do you? " He says "I know him like a brother. "  And I sat down on the sidewalk beside him and I said "what about him, why is he so  great? " The old man said "well I'll tell you. " He said "you don't know this but he could  outlast anyone in the world because he was born with a double jawbone. That's why he  had so much power and so much range, and could outlast anybody with a horn. " You  can't last forever playing a horn. You get tired. He has never gotten tired of playing.
