The trumpet player always gets the girl.
The chopper looks like a Hiller UH-12, and the trumpet player is Ray Anthony. The girl, of course, is Marilyn Monroe. Anthony played in the Glenn Miller Orchestra and is the last surviving member of that band. In addition to his studio work, Anthony was a composer and actor, and had a short-lived music variety show. You can see why—the band sounds great, he is a fantastic player, but he has zero personality.
If you are at all into big band, this program is a great primer on the history of the genre and its different styles. And the band is fantastic, with Conrad Gozzo on lead trumpet.
