Dude, that horn has been with him since high school. It made him famous in Coppell and, of course, apparently made him famous (at A&M). His enthusiasm about everything is the high point of his personality.
I would say George Mitchell was like Clark Kent sometimes with his horn rimmed glasses and his very quiet manner. People say, well, he's just a quiet leader, but then he emerges as super hero and begins to move this legislation. He led by example.
I thought, If I'm gonna run a jazz club, if I've got Miles Davis' posters in my bar, I should at least know what his horn sounds like.
With eyes up-rais'd, as one inspir'd, Pale Melancholy sate retir'd, And from her wild sequester'd seat, In notes by distance made more sweet, Pour'd thro' the mellow horn her pensive soul.
I shouldn't toot my own horn, but he who doth not toot his own horn alloweth it to remain untooteth.
Alben W. Barkley
Blow your life through your horn.
