I keep my mouthpiece when I want to warm up and there is something going on. I don't play the radio or nothing. I got a tape player in the car. I don't play it, I just and I'll do this... that will get my lips to vibrate, you know. I'll do this all the way from then til... I get to the tunnel and then I will blow my mouthpiece, you know. Then when I pick up my horn I can get a sound out of it, you know.
