"You can't play anything on a horn that Louis hasn't played." and "I love Pops" (Louis' nickname) ... Louis has been through all kinds of styles. That's good tuba, by the way. You know you can't play anything on a horn that Louis hasn't played - I mean even modern. I love his approach to the trumpet; he never sounds bad. He plays on the beat - with feeling. That's another phrase for swing. I also love the way he sings.
