I wanted to share this you you only because the possibility of having these two great musicians together is extremely rare and it also demonstrates that a “Jazzer” can sometimes step up to the occasion when called upon. As you can see, Doc realized the situation he was in and was not completely comfortable with the experience. And he did it on a Bb trumpet, not a D trumpet. To most trumpet players who have perform this number, we realize why we choose to play it on a D and not a Bb.
