louis armstrong - the music goes round and around lyrics

now you blow through here
the music go down ’round all day
and it comes out here
now you push the first valve down
the music goes down and ’round all day
and it comes out here

oh, you push the middle valve down
the music goes down around below, below, below
listen to the jazz come out
push the other valve down
the music go down ’round all day
and it comes up here
